1. this is false because 20% of 50 equals 20. I know this because I divided each group & determined the fractions by how many numbers there were, and there were 5 numbers; therefore 50/5=10, and 10 is 10% of 50. Then Chemistry is only 10% of students taking chemistry, not 20%.
2. True. Because Physics is 6 & 6×2=12 and Health Science is 12.
3. True. Because out of 50 students, 6 are taking Physics;therefore if 100 students were surveyed, then 12 students would be taking Physics. If Tripled, and 150 students were surveyed, 18 would be taking Physics.
4. False. Because half of 50 is 25, so now when you divide 50 by 1/2, you then have to divide every number in half. And everybody taking earth Science is 4; so therefore 1/2 of 4 is 2. So the answer is False.

1) the first question is going to be true becasue i mutltiplied and my answer is ten so my first question in true
2) my second question is going to be true becasue in the class of physics are only six students and in the class of health science and if you multiply 6 by 2 you get 12
3)the third answer is goint to be true becasue for every student there going to multiply by three and and if you multiply six by 3 you get 18 the answer is true
4)the fourth answer is goint to be false becasue if you multiply by three your only going to get 12 and were trying to get 25 so the the ansawer is going to be false

1.) Is true becuase 20% of 50 is 10 , first i added up all the students and got 50 , then divided 2.0 into50 and got 10.

2.) Is true becuase there is 12 students in health science and there is 6 kids in physics and 6 x 2 is 12.
3)True because for every 50 kids taking science, 6 kids are taking physics,. 6 x 3=18
4)false becuase 4 divided by 2 is 2,.

1)True, because if you divide 50 by 10.00 you will get .2o then you need to convert it into a percent.

2)True, because 12 students are taking health science and 6 students are taking physics and if you divde 12 by 6 you get 2 so that is double the amount of physics.

3)True, because say you have 50 students total over 6 physics than you go like this. Example: 50/6 + 50/6 + 50/6 you will get 150/18 like it says above for number 3.

4)False, because the total amount of students is 50 so you would have every 50 students would at least have 4 students that are taking Earth Science or if every 25 students and 4 Earth science students then that would mean that the graph up at the top would be wrong and it would say 8 to every 50 students but it doesn’t so it would be false.

The answer to number 1. is True because the sum above is 50 so times it by 2 it equals 100 so times 10 it by 2 it equals 20. chemistry is 20%.

The answer to number 2. is True because 12 divided by 2 equals 6. So 12 is twice as many as 6.

The answer to number 3. is True because the sum above is 50. 50 times 3 is 150, so 6 times 3 equals 18. So every 150 students there is 18 students.

The answer to number 4. is False because the sum above is 50 . 50 divided by 2 is 25 , so 4 divided by 2 is 2 . So no, every 25 students there is 2 not 4.

1. False, because the total amount of students are 50 and 20% of 50 is not 10 because only 10 people are taking chemistry.

2.True, because there are 12 people in health science and half of 12 is 6 so then the statement is true.

3.True, because there is a total of 50 students and for there to be 150 you have to times it by 3 so then you times the number of students taking physics is 6 so then multiply 6 by 3 and you.get 18 so then the statement is true.

4. False, because the total number of students is 50 and there are 4 taking earth science so for 25 students it would be 2 students not 4 so that statement is wrong.

1)true 2) true because 6 students are taking physics and 12 are taking health science. 3)true because 6/50 students are taking physics 4)false because 4/50 students are taking earth science and their will be 2/25 students in that class

1. True, there is 26% taking Chemistry
2. True, there is exactly twice as many students in Health Science the Physics
3. True, because 12% of 150 students would equal 18 students
4. False, there would only be 2 students in Earth Science

1. True
I got my answer by multiplying 2 into 10 and 50. I multiplied 2 into 10 and 50 because 50 had to become 100 and if I muliplied 50 by 2 then I have to do it to the numerator. So when I multiplied my results were 20 over 100. Which would be 20% of the students are taking Chemistry. That’s why I chose true.

2. True
I picked true because if you multiply 2 into 6 then it would equal 12. You would multiply by 2 because it says “twice as many.” I just had to check if 6Γ2=12 and it does so that’s why my answer is true.

3. True
This is true because every 50 students there are 6 taking physics and if you divide 150 by 50 then it would be 3. So you would multiply 6 by 3 and it equals 18. So in every 150 students there is 18 taking physics. That’s how i got my answer.

4. False
My answer is false because how is it that in every 50 students there are 4 taking earth science? So my prediction is that there will be about 2 students taking earth science in every 25 students. That’s why I chose false.

1)False, because 20% of 50 is 10.
–
2)True, because 6×2 is 12. (6 students are in physics, 12 students are in health science).
–
3)True, because every 50 students there’s 6 in physics, every 100 students there’s about 12 students in physics, and every 150 students there’s about 18 in physics.
–
4)False, because every *50* students there’s 4 in earth science. So every 25 students there would be at least 2 students in earth science

1) True because if you add all of the number of students you get 50 and if you minus 10 from 50 you’ll get 40 and if you minus 30 from 40 you get 10.
2) True because 6×2=12 and its the half of 12,(6)
3) False because it doesn’t matter how many students in total you have it matters about how many students are REALLY taking the class
4) True because even though there are 25 students theres STILL 4 of them in the class (JUST LIKE NUMBER 3)

the answer to number 1 is TRUE because 10 students is 20 percent of 50 students.the answer to number 2 is TRUE because 6 times 2 is 12. the answer to number 3 is TRUE because the graph is for 50 students so i multiplyed that by three to get 150 then i multiplyed the number of physics students by three also. the answer to number 4 is FALSE because 25 is half of 50 so i took the number of students taking earth science and divided it by 2 and i got 2 so it turned out to be false

Number 1 is true because i added all of the numbers and i looked to see if it was 20% and it was.
Number 2 is true because i took the numbers from the table put them in a ratio and saw if it was equal to1/2 and it was.
Number 3 is true because i multipyed the total amount of people so that i could get 150 and it was *3 so i multiplyed 6 by 3 and got 18.
Number 4 is false because i divided 50 by 2 and i did the same to 12 and i got 6.

for question #1 is no because no much kids wants to go on chemistry for question#2 yes because question #1 was ten for#3 is no because you can no predict that is a digger and the last question is true because you can predict that because is a smaller #.

1) False, because 50 divided by 10 is 5 and 5 times 20 100 not 50
2) True, because 6 times 2 is twelve which is the number of people in Health Science 6 are in Physics
3) True, because 50 times 3 is 150 you have to do the same thing to 6 and 6 times is 18
4) False, because for every 50 there are 4 people in Earth Science so for there to be 4 for every 25 then there would have to be 100 people

1) Yes it is true because if you divide 10 by 50, you’ll get 0.2. 0.2 is 20% and it’s true.
2)Yes it’s true because if you multiply 6 with 2 it equals 12 and there’s 12 people taking Health and 6 taking pysics
3)True because out of 50 students, 6 are taking Physics. If you do 50 times 3 then you got to do the same with 6. So out of 150 you got 18 students taking physics.
4)False because you are taking out half of fifty. Therefore you do the same to half of 4 which is 2. So out of 25 students 2 are taking Earth Science.

2.) True. I got this because .5 of 12 is 6 and there are 6 people in physics.

3.) True. I got this by multiplying 6 by 3 (because that equals 18) and I multiplied 50 by 3 (because there are 50 students and only 6 are in chemistry) and they both equalled the amount the question said ( 18 students for every 150 students.)

4.) False. Since the table has 4 already for 50 students, that’s already common sense.

1)true because if – x/100=10/50 (50 is the total amount of students) then 1000=50x, and when you solve the one step equation you get 20%
2)true-6*2= 12 and there are 12 students taking health science
3)true-there are 6 students taking phyics out of 50 students equals 18 students out of 100 students
4)false- 4 students for every 50 students equals 2 students for every 25 students

2. true because 12 studense are taking helth science and 6 studens are taking physic science, so my answer is true because twice as meny studens are taking helth science than physic science.

1)true because you double the amount of number to get 100%
2)true you double the amount of people taking for physics and get it
3)true because you would do 3*6 and get 18 and 3*50 is 150
4)false because you cant get dived 4 6 so false

1.True because 20% of 50 is 10 and ten students are taking chemistry. 2.False because double of 4 is eight not six. 3.True because 50 times 3 equals 150, and 6 times 3 equals eighteen. 4.False because since there are only 50 students, then to get to 50 from 25 you only need to multiply it by 2 and if you multiply 4 by 2 then you get 8 not twelve.

1. true because if you divide the percentage then it is right.
2.true because 6×2=12.
3.true because i multiplyed 50×3=150 then i did 6×3=18 so its true.
4.false because for 25 students 2 should be taking earth science

1) True because if you times the number of people that are taking chemistry it would be 20 and multiply 2 by 50 it would be 100 so it would be a fraction of 20/100 and be at 20%.
2) True because 12 divided by 6 is 2.
3) True because 6 times 3 is 18 since there are 50 students there needs to be 3 times the amount.
4) False because there are only 50 students and 4 students are in Earth Science.
That is my answer π

1) 10 is __ % of 50. Use the heart once you put it in fraction form
10 x. = 50x = 1000.
—- = —
50 100. 50Γ·1000= 20 so statement 1. Is TRUE because 10 is 20% of 50

2) TRUE because 6 is half of 12
_ _
3) 150Γ·18= 8.3. 6 does not equal 8.3 so the answer is FALSE.

4) 25Γ·4= 6.25. The document says AT LEAST, so 6.25 is close to 4, so im going to say its TRUE

Thanks Sydney! If you divide the total by the number of kids taking certain classes (the part) won’t you get the percentage of kids taking the classes?

1 the answer is false because there are 10 out of 50 students taking chemistry so that is only 5% no 20

2 the answer is true because 12 people are taking health science and only 6 people are taking physics and that is half of health science that’s why it is true

3 the answer is false because for only 150 there will only be about 13 people taking physics

4 the answer is false because for 50 people only 4 take earth science so for 25 there would be about 2

1.) True
Explanation: Because there are 50 students and 10 were taking Chemistry, 10/50 of the students were taking Chemistry. You can reduce 10/50 to 1/5. As a decimal 1/5 is .2 so as a percent .2 is 20%
2.) True
Explanation: 6 students are taking Physics and 12 are taking Health Science. 6 x 2 = 12 so there are double the students taking Physics in Health Science.
3.) True
Explanation: On this chart, only 50 students were surveyed, but if there are 150 students surveyed it would be 3 times the amount of what is already on the chart because 50 x 3 = 150. There are 6 students taking Physics when 50 students are surveyed, so 6 x 3 = 18.
4.) False
Explanation: There were 50 students surveyed in this chart and 4 of them were taking Earth Science, so if there were 25. which is half of 50, there would be 2, because half of four is two.

1. True. I divided the 10 students taking Chemistry by the 50 student surveyed and I got 20%.
2. True. There are 12 students taking Health Science and 6 taking Physics, so that is twice the amount of students taking the health science class. I also divided 12 into 50 and got 24% and 6 divided by 50 and got 12%.
3. True. Since there are 6 students taking Physics for the survey of 50 students, we can predict that there will be 18 for 150 students.
4. False. Since there are 4 students for the survey of 50, there would be 2 for 25 because it is half of 50 and 2 is half of 4.

1.True. Since there is 50 students total and 10 are taking chemistry I divided 10 by 50 and got 20 percent.
2.True. Since there are 12 students taking health science, and 6 students taking physics, 12 divided by 6 is 2 to show twice as many students.
3.True. Since there are 50 students total and there are 6 students taking physics, so 150 students is 50 times 3 and 6 times 3 is 18.
4.False. Since 25 students is half of 50, so half of 4 would be 2.

1.true because the total # of students is 50 and 10 is and 50 times 2 is 100, so 10β’2 is 20, %20
2.true because 12 is double the amount of 6, 6β’2=12
3.true because if there are 50 students total, then you multiply that by 3, then you multiply 6 by 3, which is 18.
4.false because 25β’2 is 50, and when you multiply 4 by 2 you get eight. So for the answer to be true, it must be for every 25 students only 2 will have earth science.

1. False because I added all the students and then got 50 so then I did 10 percent of 50 is 5%.

2. True because 12 students are taking health science and only 6 are taking physics. So I did 6 * 2 which is 12 so that is technically double of the students that are tAking physics.

3. False because I did 6 into 150 (I got the 6 from how many students are in physics ) and I got 25 students out of 150 students are most likely to go to physics.

4. False because I did 4 / 25 ( I got the four from how many students were taking earth science) and I got 6 and 1/4 for how many students are most likely going to take earth science. π ππ

Thanks Angel! #1 was asking for 20% so could you double your value you got for 10% to get the answer? For #3, if you tripled the total number of students to get 150, could you do the same with the number of students taking physics?

1) true. I found my answer by using 20 as a numerator and 50 as my denominator then i converted that into a percentage that equaled 20%

2) true. To solve this i simply divided 6 into 12 and got 2 which means double.

3) False. This is false since the data table shows a total of 50 and they are asking for 150 so you simply add 100 to your outcome of 18 and get 180 as an answer

4) false. The total of students is 50 and they are asking for 25 students which is half so you simply divide the outcome by 2 and get 2 as an answer.

1) Because there are 50 students total,and 10 students are taking chemistry, then about 20% of the students are taking chemistry. True.
2)12 (health science) is double then 6 (physics) The answer is true.
3)The answer is true because 50 multiplied by 3 is 150, and 6 multiplied by 3 is 18.
4)This statement is false because even at 50 there are only 4 taking earth science.

1) True
Solution:10/50=1/5×100=5/100=20
2) True
Solution: Health Science=12 Physics=6 divide 12/6=2 twice as much
3)True
Solution:150/50=3 3×6=18
4)False
Solution 50/25=2.You reduce by 2 and you divide 4/2 to get 2 students in Earth Science. It says “at least” that means minimum 4 students.

1. False- this is false because if you do the math correctly you know that in percentages it means per hundred so since there was 50 students who took the survey you had to divide 100 by 50 and the correct answer is 2% not 20%.

2. True-this is true because 12 students are taking health science and 6 students are taking physics. So what I did was multiply 6 by 2 because the problem said about twice as many students and the answer was 12.

3. True- this is true because every 50 students 6 take physics so, the problem wants to know about every 150 students. What i did was divide 150 by 50 which equals 3 because we need to know if 18 students are taking physics then i multiplied 3 by 6 it equaled 18.

4.false-this is false because first of all you need 50 students not 25 and if it were 25 it would be every 2 students because 25 is half of 50.

Thanks Susy! I like how you connected % to out of 100! Could you double 50 to make it 100 and then double the number of kids taking the subject as well to get your percent?

1.true because i put 50/100 and got 0.5. then i multiplied 0.5 and 20 and got 10, so 20% of students took chemistry.
2.true because health science has 12 people and physics has 6 and we know that 12 is just 6 times 2.
3.true because i counted 50 students and multiplied that by 3 and got 150.then i took 6 and multiplied it by 6 and got 18 students.
4.false because i took 50 and split it so it becomes 25 and i split the kids in earth science which was 4 and it turned to 2 so that is false.

1) 20 ‘/. Of the people taking science classes are taking chemistry, because 50 divided by 20’/. = 10 which there r 10 people taking chemistry.
2) true 2s as much people r taking health than phisics, because 6 times 2 =12.
3)true because u r survaing 50 and 50 times 3 is 150 so u would just times that by 3 also and u get18.
4) false because 4 out of 50 r taking earth science so the right answer would be 2 out of 25 people r taking earth science.

1) Number one is True because since there are 50 students in total and 10 would be 20% because 20%x5 would be 100%.
2) Number two would be True because 6 is half of 12 so Half as many students are taking Health Science than Physics.
3) Number three would be True because since there are 50 students in total and if there would be 150 then it would be times three and it would be true because 6×3=18.
4) Number four is False because its not for every 25 students it is not 4 its for every 50 student it is 4.

1) true , because 10 is the starting number and you are counting by tens so 20 would be the next number then 30 , 40 and then 50 so when you get to 50 you know its true.
2) true, because because half of 12 is 6 and 6 times 2 is 12 so it is twice as much.
3) true , because 50 times 3 is 150 and 6 students are taking physics so when you multiply that by 3 so it gets to 150 it is 18.
4) false, because 25 is half of 50 so you would have to take have the points of on earth science and it would be 6 not 4 so that is false.

1)True, because when I tried to find the 20% of 50 I got 10.First I knew that 20% is 20/100 and ?/50 I knew that 50β’2=100 so I divided both 100 and 20 by 2 and got 10/50.
2) True, because I multiplied 2 and 6 because 6 is the physics and 2 is the twice so I got 12 and it was true.
3)True, because I knew that 6= 50 students and were looking for
?=150 I knew that 50 β’3=150 so I multiplied 6 and 3 and got 150.
4)False, because 4 students are taking Earth science out of 50. I knew that to get to 25 students you divide 50 and 25 so I divided 4 and 2 i got 2 so the answer is false.

1) True, because 10 is 20% of the class
2) False, because not twice as many are taking that class
3) Flase, because if you look at the chart its not true
4) True, because the chart shows it

1) true because 10 is 20% of the class
2) false because not 2 as many students are taking that class
3) false because it does not show that
4) true becasue it shows it on the chart of classes

1) Number 1 is false because instead of being about 20% its actually 10%.
2) Number 2 is true because twice as many students are taking health science than they are taking physics.
3) Number 3 is false because only 6 people are taking physics so than it would not all add up to 150.
4) Number 4 is true because their is 4 students who are taking earth science so it just makes sence.

Thanks Tony! Can you figure out how many students are involved with the classes listed? Could you use that as your total amount? If you don’t understand a problem, I am in my class everyday at lunch! Stop by and I’ll give you a little help. π

1. True because 10 students taking chemistry is 20% of 50 total students. 10/50 = .20 = 20%

2. True because there are 6 students taking physics and 12 students taking health science and 12/6 = 2

3.True because 150 students is 3 times as many students as 50 so if there are 6 students out of 50 taking physics then there woukd be 3 x 6 =18 fir every 150 students

4. False because 25 is half of 50 students and for every 50 students 4 are taking earth science so for every 25 students 4/2 = 2 would take earth science.

1) it is true because 20 percent of 50 is 10.
2) it is true because half of 12 is 6, and 6 people are taking physics
3)it is true because 150 of 50 is 3 & 3 times 6 is 18
4) it Is false because in 25 there should only be 2

#1 is false because since there is 50 students and there is only 5 classes 20 percent would be 20 students in a class and there is only 10 students in the class # 2 would be true because there is 6 students in physics and 12 students in health and if you will multiply 6 by 2 you will get 12 # 3 is true because since 50 students got surveyed the only way to get from 50 to 150 is to multiply by 3 so u will multiply 6 (because that’s how many people are in physics) by 3 and get 18 and # 4 is false because there is already 4 students in earth science and IF every 25 students they four of them would be in earth science that would mean there would be 8 students in earth science but there is not there is only 4

Thanks Jaylice! In #1, you are trying to find 20% of the total number of students not how many classes. Make sure you read the questions very carefully!

1) True
The answer is true because when you double 50 so it can become 100%, 10 becomes 20%.
2)True
The answer is true because 6 doubled is 12.
3)True
The answer is true because 50*3 is 150, so you would multiply 6*3 and then get 18.
4)False
The answer is false because half of 50 is 25, and half of 4 is not 4 but 2.

1) The answer is true because 20% of 100 is 20. Since 50 is half of 100, and half of 20 is 10, then 20% of 50 is 10.

2)The answer is true. 12 students are taking health science, and 6 students are taking physics. Half of 12 is 6, so twice as much of 6 is 12.

3)The answer is true. 150 is three times as much as 50. If you multiply the number of students taking physics, then you would get the amount of students that would take physics out of 150 students 6 times 3 is eighteen, so the answer is true.

4)The answer is false. Since you are doing every 25 students, then you divide 50 by 2 to get 25. Then, since there are 4 students taking Earth Science for every 50 students, then you would divide 4 by 2, the product is 2, not 4.

1)True, Because 20% of 50 is 10% out of all the students.

2)True, Because in Physics there are 6 students taking that class and in Health class there are 12 students. So yes there are twice as many students that are taking health class.

3)True, Because if you multiply all 50 students by 3 it will be 150. Because there are 6 kids in Physics and 6 times 3 is 18.

4)False, Because if you divide 50 by 2 to get 25 you would have to divide all the student classes by 2 causing 4 to become 2 instead of 4 for every 25.

1) true, because if you take 50 students and make it a percent its 0.5 so then divided by 20 for 20% of students taking chemistry its 0.025 so thats about 20%.
2) true, because 6 are taking physics and 12 are taking health science so twice as many are taking health science. (6+6=12)
3) true, because if you do 50*3 you get 150 and if you do 6*3 you get 18. so for every 150 students you could maybe get at least 18 of students. you are taking each number and multiplying it by 3.
4) false, because if you take 50 divided by 25 you get 2 and if you take 4*2 you get 8. i took 2 because thats how many times 25 goes into 50 and your total is 50 students so out of 25 itd be 2 and so there saying you could get 4 out of that but you really cant because 4*2 is 8.

1)the answer is true because 10 divided by 50 is .2 which is 20%
2)The answer is true because12 divided by 2 is 6 and that is half of 12
3)the answer is true because 50 multipled by 3 is 150 and 6 multipled by 3 is 18… So every 150 at least 18 are taking physics.
4)the answer is 4 because half of 50 is 25 so it would be 2 students take earth science, for every 25 students.

1) the answer is true because 10 divided by 50 is .2 which is 20%.
2) True because 6 are taking physics and 12 are taking health science. 6 times 2 equals 12 (6*2=12).
3) True because 50*3=150 and 6*3=18.
4) False because for every 50 students 4 are taking Earth Science. So for every 25 students about 2 would will take Earth Science.

1) True, 10 is 20% of 50
2) True, 6 is half of 12
3) False, 50 times 3 is 150, whereas 4 times 3 is not 18
4) False, for every 25 kids, 2 are taking earth science

1) False, because 50 divided by 10 is 5 and 5 times 20 100 not 50
2) True, because 6 times 2 is twelve which is the number of people in Health Science 6 are in Physics
3) True, because 50 times 3 is 150 you have to do the same thing to 6 and 6 times is 18
4) False, because for every 50 there are 4 people in Earth Science so for there to be 4 for every 25 then there would have to be 100 people

(1) true:10 out of 50 is 20% (2)true:12/6 =2 which is .5 of 12
(3)true:6*3=18 and 150 is 3 of the data charts
(4)false:25 is half of 50 so there would be 2 students in Earth
Science.
FINAL ANSWER!!!!!!!!!!

# 1 .Is true because you can divide 50 by 20 and you get 10.
#2. Is true because 6 times 2 equals 12 which is twice as many people doing health science then instead of physics .
#3.Is true because the 50 are doing physics.
#4.Is false because it’s not every 25 people i think it every 50 people.

2.)True: Cause there are 12 students in Health Science and 1/2 of 12= 6.

3.)True: There is a total of 50 students and for there to be 150 you have to multiply by 3; Then you multiply the amount of students taking Physics which is 6; Last multiply 6 by 3=18.

4.)False: Cause the total number of students is 50 and there are 4 taking Earth Science…for 25 students it would be 2 students and not 4 so this is wrong.

i think the answers are
1.true
2.true
3.true
4.faulse
on the frist one if yo take 50 student then make it to 0.5 and divied by 20 yu will get 20%.
students thant are taking physics are 6 and the ones that are taking health sceinece are 12 so 6+6=12.i
if you take 50(3) you will get 15 and if you do 6(3) you will get18
if yu get 50/2 you will get 10

1) True: If 15 students were taking chemistry that would be 25% so 10 students would be 20%.
2)True:6 is half of 12
3)True: 6(3) is 18 and 50(3) is 150
4)False: There are 4 when there are 50 students so if 25 is half of 50 then I would predict 2 students taking Earth Science.

false, I am guessing because I don’t know how to solve it.
true, because there are 6 students taking physics. 6*2=12. 12 students are talking health science.
false, because if you do the math (that’s below) the answer is 27 not 18.
false, because there are all ready 4 taking earth science.

1)this is true,cause 20 percent of 50 is 10 percent out of all the students
2)I think its true, cause six doubled is twelve
3)I think this is true cause if you times all 50 (students) by 3 the answer will be 150 cause there is 6 students in physics , 6 x 3=18
4)I don’t know this one ?

1) true because 20 percent of 50 is 10
2)true bacause half of 12 is 6,and 6 people are taking physics.
3)true bacause 150 of 50 is 3 & 3 times 6 is 18
4)false because in 25 there should only be 2.

True because I multiplied 50 and .20 and got 10
True because .5 of 12 is 6 and there is 6 students in physics
True because if you multiply 6 by 3 (you will get 18) and then I multiplied 50 by 3 because there Are 50 students and only 6 in chemistry and both equalled the amount the question said.
False because 4 students for every 50 students EQUALS 2 students for every 25 students.

True because I multiplied 50 by .20 and my answer was 10.
True because when you divide 12 by 6 your answer is 6.
True because 150 of 50 is 3 .And 3 times 6 is 18.
False because 4 for every 50 students is 2 for every 25 students.

1. True because 50 multiplyed by 20 and i have 10
2. true becasue 5 of 12 is 6 and there is 6 students in physics
3. true because if you multiply 6 and 3 and your answer is 18 and the multiply 50 by 3 because there are 50 students and 6 in chemistry and both are equal
4. false because 4 students for every 50 sudents is equal to 2 students for every 25

1) true 2) true because 6 students are taking physics and 12 are takinghealth science . 3) true because 6/50 students are taking physics . 4) false because 4/50 students are taking earth science and there will be 2/25 students in that class.

True because I multiplied 50 and .20 and got 10
True because .5 of 12 is 6 and there is 6 students in physics
True because if you multiply 6 by 3 (you will get 18) and then I multiplied 50 by 3 because there Are 50 students and only 6 in chemistry and both equalled the amount the question said.
False because 4 students for every 50 students EQUALS 2 students for every 25 students.

The Literacy Shed
This is where we will find many of our writing prompts. If you see one you want to write about, let me know and we will check it out in class!

1) false beause, if you add 18, 12, 10, 6, 4,you get 50. but then you divide 10 into 50 and get 5 not 20.

2) false beause,if you multiply 25 and 3 you get 75 but then you divide 4 into 75 but you do not get 75.

3) true beause,if you multiply 50 and 3 you get 150 but then multiply6 and 3you will get 18.

4) true beause, if you divide 25 and 4 you do not get 4 but you can look on the table it wil show that four people are taking earth science.

1. this is false because 20% of 50 equals 20. I know this because I divided each group & determined the fractions by how many numbers there were, and there were 5 numbers; therefore 50/5=10, and 10 is 10% of 50. Then Chemistry is only 10% of students taking chemistry, not 20%.

2. True. Because Physics is 6 & 6×2=12 and Health Science is 12.

3. True. Because out of 50 students, 6 are taking Physics;therefore if 100 students were surveyed, then 12 students would be taking Physics. If Tripled, and 150 students were surveyed, 18 would be taking Physics.

4. False. Because half of 50 is 25, so now when you divide 50 by 1/2, you then have to divide every number in half. And everybody taking earth Science is 4; so therefore 1/2 of 4 is 2. So the answer is False.

i think its a because 20 ./. percent took chemistry and if you add some of them up at a time yall get the right awnser

Thanks Onterio! Make sure you completely answer the blog. Have another look at the questions please!

1) the first question is going to be true becasue i mutltiplied and my answer is ten so my first question in true

2) my second question is going to be true becasue in the class of physics are only six students and in the class of health science and if you multiply 6 by 2 you get 12

3)the third answer is goint to be true becasue for every student there going to multiply by three and and if you multiply six by 3 you get 18 the answer is true

4)the fourth answer is goint to be false becasue if you multiply by three your only going to get 12 and were trying to get 25 so the the ansawer is going to be false

1)The answer is going to be true because 10 is going to be the answer and ten is a good for the varlble.

2)The answer is going to be true because when you put the answer in then you get the correct answer.

3)The answer is going to be true because if you times 6 x 3=18.

4)The answer is going to incorrect because if you times 4 x4= you dont get 24.

1.) Is true becuase 20% of 50 is 10 , first i added up all the students and got 50 , then divided 2.0 into50 and got 10.

2.) Is true becuase there is 12 students in health science and there is 6 kids in physics and 6 x 2 is 12.

3)True because for every 50 kids taking science, 6 kids are taking physics,. 6 x 3=18

4)false becuase 4 divided by 2 is 2,.

1)True, because if you divide 50 by 10.00 you will get .2o then you need to convert it into a percent.

2)True, because 12 students are taking health science and 6 students are taking physics and if you divde 12 by 6 you get 2 so that is double the amount of physics.

3)True, because say you have 50 students total over 6 physics than you go like this. Example: 50/6 + 50/6 + 50/6 you will get 150/18 like it says above for number 3.

4)False, because the total amount of students is 50 so you would have every 50 students would at least have 4 students that are taking Earth Science or if every 25 students and 4 Earth science students then that would mean that the graph up at the top would be wrong and it would say 8 to every 50 students but it doesn’t so it would be false.

The answer to number 1. is True because the sum above is 50 so times it by 2 it equals 100 so times 10 it by 2 it equals 20. chemistry is 20%.

The answer to number 2. is True because 12 divided by 2 equals 6. So 12 is twice as many as 6.

The answer to number 3. is True because the sum above is 50. 50 times 3 is 150, so 6 times 3 equals 18. So every 150 students there is 18 students.

The answer to number 4. is False because the sum above is 50 . 50 divided by 2 is 25 , so 4 divided by 2 is 2 . So no, every 25 students there is 2 not 4.

1) is true because IF YOU ADD ALL UP IT EQUALS 50 SO THE RULE IS TIMES 2 and what is 10 times 2? 20!

2)is true because again with the rule and what is 24 divided be 2?

ABOUT HALF

3) is true because 50 times 3 and 6 times 3 IS 18

4) is false because 50 divided by 2 is 25 and 4 divided by is 2!

1. False, because the total amount of students are 50 and 20% of 50 is not 10 because only 10 people are taking chemistry.

2.True, because there are 12 people in health science and half of 12 is 6 so then the statement is true.

3.True, because there is a total of 50 students and for there to be 150 you have to times it by 3 so then you times the number of students taking physics is 6 so then multiply 6 by 3 and you.get 18 so then the statement is true.

4. False, because the total number of students is 50 and there are 4 taking earth science so for 25 students it would be 2 students not 4 so that statement is wrong.

Thanks Allyson! Can you have another look at the data and your answer for #1 please. π

1)true 2) true because 6 students are taking physics and 12 are taking health science. 3)true because 6/50 students are taking physics 4)false because 4/50 students are taking earth science and their will be 2/25 students in that class

Thanks Kai! Can you explain how you arrived at your solution to #1?

1. True, there is 26% taking Chemistry

2. True, there is exactly twice as many students in Health Science the Physics

3. True, because 12% of 150 students would equal 18 students

4. False, there would only be 2 students in Earth Science

1. True

I got my answer by multiplying 2 into 10 and 50. I multiplied 2 into 10 and 50 because 50 had to become 100 and if I muliplied 50 by 2 then I have to do it to the numerator. So when I multiplied my results were 20 over 100. Which would be 20% of the students are taking Chemistry. That’s why I chose true.

2. True

I picked true because if you multiply 2 into 6 then it would equal 12. You would multiply by 2 because it says “twice as many.” I just had to check if 6Γ2=12 and it does so that’s why my answer is true.

3. True

This is true because every 50 students there are 6 taking physics and if you divide 150 by 50 then it would be 3. So you would multiply 6 by 3 and it equals 18. So in every 150 students there is 18 taking physics. That’s how i got my answer.

4. False

My answer is false because how is it that in every 50 students there are 4 taking earth science? So my prediction is that there will be about 2 students taking earth science in every 25 students. That’s why I chose false.

1)False, because 20% of 50 is 10.

–

2)True, because 6×2 is 12. (6 students are in physics, 12 students are in health science).

–

3)True, because every 50 students there’s 6 in physics, every 100 students there’s about 12 students in physics, and every 150 students there’s about 18 in physics.

–

4)False, because every *50* students there’s 4 in earth science. So every 25 students there would be at least 2 students in earth science

Thanks Katie! Have a look at the data and your answer for #1 again please!

I’m fixing my answer for #1. It’s true because 20% of 50 is 10. And 10 people are taking chemistry.

1) True because if you add all of the number of students you get 50 and if you minus 10 from 50 you’ll get 40 and if you minus 30 from 40 you get 10.

2) True because 6×2=12 and its the half of 12,(6)

3) False because it doesn’t matter how many students in total you have it matters about how many students are REALLY taking the class

4) True because even though there are 25 students theres STILL 4 of them in the class (JUST LIKE NUMBER 3)

Thanks Ashleigh! Can you explain your thinking a bit more on #3?

1) the answer is true because 10 divided by 50 is .2 which is 20%.

2 )the answer is true because 12 divided by 2 is 6 and that is half of 12.

3) the answer is true because 50 multiplied by 3 is 150 and 6 multiplied by 3 is 18 so for every 150 students at least 18 are taking physics.

4) the answer is 4 because half of 50 is 25 so it would be 2 students are taking earth science for every 25 students.

the answer to number 1 is TRUE because 10 students is 20 percent of 50 students.the answer to number 2 is TRUE because 6 times 2 is 12. the answer to number 3 is TRUE because the graph is for 50 students so i multiplyed that by three to get 150 then i multiplyed the number of physics students by three also. the answer to number 4 is FALSE because 25 is half of 50 so i took the number of students taking earth science and divided it by 2 and i got 2 so it turned out to be false

so, I think the answer is number two because there are twice as much students who did take heath science than phisycs

Thanks Emma! Read the problem carefully! You need to answer and justify EACH problem!

1:False 2:true 3:false 4:true

some show and some dont

Thanks Cameron! Can you explain how you arrived at your solutions?

Number 1 is true because i added all of the numbers and i looked to see if it was 20% and it was.

Number 2 is true because i took the numbers from the table put them in a ratio and saw if it was equal to1/2 and it was.

Number 3 is true because i multipyed the total amount of people so that i could get 150 and it was *3 so i multiplyed 6 by 3 and got 18.

Number 4 is false because i divided 50 by 2 and i did the same to 12 and i got 6.

1. false

2. true

3.false

4.false

Thanks Dustin! Can you explain how you arrived at your solutions?

for question #1 is no because no much kids wants to go on chemistry for question#2 yes because question #1 was ten for#3 is no because you can no predict that is a digger and the last question is true because you can predict that because is a smaller #.

Thanks Lisbeth! Can you expain the math you used to find your solutions?

1) False, because 50 divided by 10 is 5 and 5 times 20 100 not 50

2) True, because 6 times 2 is twelve which is the number of people in Health Science 6 are in Physics

3) True, because 50 times 3 is 150 you have to do the same thing to 6 and 6 times is 18

4) False, because for every 50 there are 4 people in Earth Science so for there to be 4 for every 25 then there would have to be 100 people

Thanks Trey! Can you explain a bit further what you did with #1?

1) Yes it is true because if you divide 10 by 50, you’ll get 0.2. 0.2 is 20% and it’s true.

2)Yes it’s true because if you multiply 6 with 2 it equals 12 and there’s 12 people taking Health and 6 taking pysics

3)True because out of 50 students, 6 are taking Physics. If you do 50 times 3 then you got to do the same with 6. So out of 150 you got 18 students taking physics.

4)False because you are taking out half of fifty. Therefore you do the same to half of 4 which is 2. So out of 25 students 2 are taking Earth Science.

false because 10 is not 20%

true because 6 times 2 =12

true because lots are taking physics

false because the total is not 25

Oh no! Who does this post belong to?

1.) True. I got this because 50 x .20 = 10

2.) True. I got this because .5 of 12 is 6 and there are 6 people in physics.

3.) True. I got this by multiplying 6 by 3 (because that equals 18) and I multiplied 50 by 3 (because there are 50 students and only 6 are in chemistry) and they both equalled the amount the question said ( 18 students for every 150 students.)

4.) False. Since the table has 4 already for 50 students, that’s already common sense.

1-false 2-true 3-false4-true

Thanks Brandon! Can you explain how you arrived at your solutions?

1)true because if – x/100=10/50 (50 is the total amount of students) then 1000=50x, and when you solve the one step equation you get 20%

2)true-6*2= 12 and there are 12 students taking health science

3)true-there are 6 students taking phyics out of 50 students equals 18 students out of 100 students

4)false- 4 students for every 50 students equals 2 students for every 25 students

i think that the answers are

1.true

2.true

3.false

4.true

Thanks Michelle! Can you explain how you arrived at your solutions?

2. true because 12 studense are taking helth science and 6 studens are taking physic science, so my answer is true because twice as meny studens are taking helth science than physic science.

1)true because you double the amount of number to get 100%

2)true you double the amount of people taking for physics and get it

3)true because you would do 3*6 and get 18 and 3*50 is 150

4)false because you cant get dived 4 6 so false

1.True because 20% of 50 is 10 and ten students are taking chemistry. 2.False because double of 4 is eight not six. 3.True because 50 times 3 equals 150, and 6 times 3 equals eighteen. 4.False because since there are only 50 students, then to get to 50 from 25 you only need to multiply it by 2 and if you multiply 4 by 2 then you get 8 not twelve.

Thanks Tea! Make sure that you double check your data and that you are looking in the correct section. π

1. true because if you divide the percentage then it is right.

2.true because 6×2=12.

3.true because i multiplyed 50×3=150 then i did 6×3=18 so its true.

4.false because for 25 students 2 should be taking earth science

1) True because if you times the number of people that are taking chemistry it would be 20 and multiply 2 by 50 it would be 100 so it would be a fraction of 20/100 and be at 20%.

2) True because 12 divided by 6 is 2.

3) True because 6 times 3 is 18 since there are 50 students there needs to be 3 times the amount.

4) False because there are only 50 students and 4 students are in Earth Science.

That is my answer π

1) 10 is __ % of 50. Use the heart once you put it in fraction form

10 x. = 50x = 1000.

—- = —

50 100. 50Γ·1000= 20 so statement 1. Is TRUE because 10 is 20% of 50

2) TRUE because 6 is half of 12

_ _

3) 150Γ·18= 8.3. 6 does not equal 8.3 so the answer is FALSE.

4) 25Γ·4= 6.25. The document says AT LEAST, so 6.25 is close to 4, so im going to say its TRUE

Thanks Sydney! If you divide the total by the number of kids taking certain classes (the part) won’t you get the percentage of kids taking the classes?

1 the answer is false because there are 10 out of 50 students taking chemistry so that is only 5% no 20

2 the answer is true because 12 people are taking health science and only 6 people are taking physics and that is half of health science that’s why it is true

3 the answer is false because for only 150 there will only be about 13 people taking physics

4 the answer is false because for 50 people only 4 take earth science so for 25 there would be about 2

Thanks Audra! Can you explain how you arrived at your solutions?

1.) True

Explanation: Because there are 50 students and 10 were taking Chemistry, 10/50 of the students were taking Chemistry. You can reduce 10/50 to 1/5. As a decimal 1/5 is .2 so as a percent .2 is 20%

2.) True

Explanation: 6 students are taking Physics and 12 are taking Health Science. 6 x 2 = 12 so there are double the students taking Physics in Health Science.

3.) True

Explanation: On this chart, only 50 students were surveyed, but if there are 150 students surveyed it would be 3 times the amount of what is already on the chart because 50 x 3 = 150. There are 6 students taking Physics when 50 students are surveyed, so 6 x 3 = 18.

4.) False

Explanation: There were 50 students surveyed in this chart and 4 of them were taking Earth Science, so if there were 25. which is half of 50, there would be 2, because half of four is two.

1. True. I divided the 10 students taking Chemistry by the 50 student surveyed and I got 20%.

2. True. There are 12 students taking Health Science and 6 taking Physics, so that is twice the amount of students taking the health science class. I also divided 12 into 50 and got 24% and 6 divided by 50 and got 12%.

3. True. Since there are 6 students taking Physics for the survey of 50 students, we can predict that there will be 18 for 150 students.

4. False. Since there are 4 students for the survey of 50, there would be 2 for 25 because it is half of 50 and 2 is half of 4.

1.True. Since there is 50 students total and 10 are taking chemistry I divided 10 by 50 and got 20 percent.

2.True. Since there are 12 students taking health science, and 6 students taking physics, 12 divided by 6 is 2 to show twice as many students.

3.True. Since there are 50 students total and there are 6 students taking physics, so 150 students is 50 times 3 and 6 times 3 is 18.

4.False. Since 25 students is half of 50, so half of 4 would be 2.

1.true because the total # of students is 50 and 10 is and 50 times 2 is 100, so 10β’2 is 20, %20

2.true because 12 is double the amount of 6, 6β’2=12

3.true because if there are 50 students total, then you multiply that by 3, then you multiply 6 by 3, which is 18.

4.false because 25β’2 is 50, and when you multiply 4 by 2 you get eight. So for the answer to be true, it must be for every 25 students only 2 will have earth science.

1. False because I added all the students and then got 50 so then I did 10 percent of 50 is 5%.

2. True because 12 students are taking health science and only 6 are taking physics. So I did 6 * 2 which is 12 so that is technically double of the students that are tAking physics.

3. False because I did 6 into 150 (I got the 6 from how many students are in physics ) and I got 25 students out of 150 students are most likely to go to physics.

4. False because I did 4 / 25 ( I got the four from how many students were taking earth science) and I got 6 and 1/4 for how many students are most likely going to take earth science. π ππ

Thanks Angel! #1 was asking for 20% so could you double your value you got for 10% to get the answer? For #3, if you tripled the total number of students to get 150, could you do the same with the number of students taking physics?

1) true. I found my answer by using 20 as a numerator and 50 as my denominator then i converted that into a percentage that equaled 20%

2) true. To solve this i simply divided 6 into 12 and got 2 which means double.

3) False. This is false since the data table shows a total of 50 and they are asking for 150 so you simply add 100 to your outcome of 18 and get 180 as an answer

4) false. The total of students is 50 and they are asking for 25 students which is half so you simply divide the outcome by 2 and get 2 as an answer.

Thanks Citlally! If they are asking for 3 times the total number of students, would you add?

1) Because there are 50 students total,and 10 students are taking chemistry, then about 20% of the students are taking chemistry. True.

2)12 (health science) is double then 6 (physics) The answer is true.

3)The answer is true because 50 multiplied by 3 is 150, and 6 multiplied by 3 is 18.

4)This statement is false because even at 50 there are only 4 taking earth science.

1) True

Solution:10/50=1/5×100=5/100=20

2) True

Solution: Health Science=12 Physics=6 divide 12/6=2 twice as much

3)True

Solution:150/50=3 3×6=18

4)False

Solution 50/25=2.You reduce by 2 and you divide 4/2 to get 2 students in Earth Science. It says “at least” that means minimum 4 students.

1.True because 10 people out of fifty would be 20% out of 100%.

2.False because there is actually half of Health Science.

3.True because if you multiply id by 3 you would get 18.

4.False I think that it would be a bit more because if you split it up as it is right now it would be a bit more than 4.

Thanks Christian! Can you explain a little more about how you arrived at your solutions?

1. False- this is false because if you do the math correctly you know that in percentages it means per hundred so since there was 50 students who took the survey you had to divide 100 by 50 and the correct answer is 2% not 20%.

2. True-this is true because 12 students are taking health science and 6 students are taking physics. So what I did was multiply 6 by 2 because the problem said about twice as many students and the answer was 12.

3. True- this is true because every 50 students 6 take physics so, the problem wants to know about every 150 students. What i did was divide 150 by 50 which equals 3 because we need to know if 18 students are taking physics then i multiplied 3 by 6 it equaled 18.

4.false-this is false because first of all you need 50 students not 25 and if it were 25 it would be every 2 students because 25 is half of 50.

Thanks Susy! I like how you connected % to out of 100! Could you double 50 to make it 100 and then double the number of kids taking the subject as well to get your percent?

1.true because i put 50/100 and got 0.5. then i multiplied 0.5 and 20 and got 10, so 20% of students took chemistry.

2.true because health science has 12 people and physics has 6 and we know that 12 is just 6 times 2.

3.true because i counted 50 students and multiplied that by 3 and got 150.then i took 6 and multiplied it by 6 and got 18 students.

4.false because i took 50 and split it so it becomes 25 and i split the kids in earth science which was 4 and it turned to 2 so that is false.

1) 20 ‘/. Of the people taking science classes are taking chemistry, because 50 divided by 20’/. = 10 which there r 10 people taking chemistry.

2) true 2s as much people r taking health than phisics, because 6 times 2 =12.

3)true because u r survaing 50 and 50 times 3 is 150 so u would just times that by 3 also and u get18.

4) false because 4 out of 50 r taking earth science so the right answer would be 2 out of 25 people r taking earth science.

1] True 50 divided by 20 is 10.

2] True 6 multiplied by 2 is 12 twice as much.

3] False

4] False

Thanks Eliano! Make sure you include how you found ALL your solutions!

1) TRUE I 10% of 50 is 5 that means that 20% of 50% is 10.

2) TRUE 6+6=12, so yes there are twice the people taking Heath Science then Physics.

3) TRUE So there are 6 kids out of 50 already doing physics. 150/50=3, so 18/6=3.

4) FALSE There are already 4 kids taking Earth Science & 4*3=12 NOT 4.

Samantha B.

1) Number one is True because since there are 50 students in total and 10 would be 20% because 20%x5 would be 100%.

2) Number two would be True because 6 is half of 12 so Half as many students are taking Health Science than Physics.

3) Number three would be True because since there are 50 students in total and if there would be 150 then it would be times three and it would be true because 6×3=18.

4) Number four is False because its not for every 25 students it is not 4 its for every 50 student it is 4.

1) true , because 10 is the starting number and you are counting by tens so 20 would be the next number then 30 , 40 and then 50 so when you get to 50 you know its true.

2) true, because because half of 12 is 6 and 6 times 2 is 12 so it is twice as much.

3) true , because 50 times 3 is 150 and 6 students are taking physics so when you multiply that by 3 so it gets to 150 it is 18.

4) false, because 25 is half of 50 so you would have to take have the points of on earth science and it would be 6 not 4 so that is false.

1)True, because when I tried to find the 20% of 50 I got 10.First I knew that 20% is 20/100 and ?/50 I knew that 50β’2=100 so I divided both 100 and 20 by 2 and got 10/50.

2) True, because I multiplied 2 and 6 because 6 is the physics and 2 is the twice so I got 12 and it was true.

3)True, because I knew that 6= 50 students and were looking for

?=150 I knew that 50 β’3=150 so I multiplied 6 and 3 and got 150.

4)False, because 4 students are taking Earth science out of 50. I knew that to get to 25 students you divide 50 and 25 so I divided 4 and 2 i got 2 so the answer is false.

1.false

2.true

3.false

4.true

the data table really helps you with the answers and it is actually really easy!!!!!!!!!!

Thanks Maria! How did you find your solutions?

1) True, because 10 is 20% of the class

2) False, because not twice as many are taking that class

3) Flase, because if you look at the chart its not true

4) True, because the chart shows it

Thanks Jimena! How did you find your solutions?

1) true because 10 is 20% of the class

2) false because not 2 as many students are taking that class

3) false because it does not show that

4) true becasue it shows it on the chart of classes

Thanks Alexa! How did you find your solutions?

1) Number 1 is false because instead of being about 20% its actually 10%.

2) Number 2 is true because twice as many students are taking health science than they are taking physics.

3) Number 3 is false because only 6 people are taking physics so than it would not all add up to 150.

4) Number 4 is true because their is 4 students who are taking earth science so it just makes sence.

Thanks Ana! How did you find your answer for #1, 3, and 4?

1) False, it says nothing about the whole high school

2) True, there’re 12 students taking health science and 6 taking physics

3) ? I don’t get tat one

4) False, because there just only 4 not 8 or 16 or 20 ect

Thanks Tony! Can you figure out how many students are involved with the classes listed? Could you use that as your total amount? If you don’t understand a problem, I am in my class everyday at lunch! Stop by and I’ll give you a little help. π

1. True because 10 students taking chemistry is 20% of 50 total students. 10/50 = .20 = 20%

2. True because there are 6 students taking physics and 12 students taking health science and 12/6 = 2

3.True because 150 students is 3 times as many students as 50 so if there are 6 students out of 50 taking physics then there woukd be 3 x 6 =18 fir every 150 students

4. False because 25 is half of 50 students and for every 50 students 4 are taking earth science so for every 25 students 4/2 = 2 would take earth science.

1) it is true because 20 percent of 50 is 10.

2) it is true because half of 12 is 6, and 6 people are taking physics

3)it is true because 150 of 50 is 3 & 3 times 6 is 18

4) it Is false because in 25 there should only be 2

#1 is false because since there is 50 students and there is only 5 classes 20 percent would be 20 students in a class and there is only 10 students in the class # 2 would be true because there is 6 students in physics and 12 students in health and if you will multiply 6 by 2 you will get 12 # 3 is true because since 50 students got surveyed the only way to get from 50 to 150 is to multiply by 3 so u will multiply 6 (because that’s how many people are in physics) by 3 and get 18 and # 4 is false because there is already 4 students in earth science and IF every 25 students they four of them would be in earth science that would mean there would be 8 students in earth science but there is not there is only 4

Thanks Jaylice! In #1, you are trying to find 20% of the total number of students not how many classes. Make sure you read the questions very carefully!

1) True

The answer is true because when you double 50 so it can become 100%, 10 becomes 20%.

2)True

The answer is true because 6 doubled is 12.

3)True

The answer is true because 50*3 is 150, so you would multiply 6*3 and then get 18.

4)False

The answer is false because half of 50 is 25, and half of 4 is not 4 but 2.

1) The answer is true because 20% of 100 is 20. Since 50 is half of 100, and half of 20 is 10, then 20% of 50 is 10.

2)The answer is true. 12 students are taking health science, and 6 students are taking physics. Half of 12 is 6, so twice as much of 6 is 12.

3)The answer is true. 150 is three times as much as 50. If you multiply the number of students taking physics, then you would get the amount of students that would take physics out of 150 students 6 times 3 is eighteen, so the answer is true.

4)The answer is false. Since you are doing every 25 students, then you divide 50 by 2 to get 25. Then, since there are 4 students taking Earth Science for every 50 students, then you would divide 4 by 2, the product is 2, not 4.

1)True, Because 20% of 50 is 10% out of all the students.

2)True, Because in Physics there are 6 students taking that class and in Health class there are 12 students. So yes there are twice as many students that are taking health class.

3)True, Because if you multiply all 50 students by 3 it will be 150. Because there are 6 kids in Physics and 6 times 3 is 18.

4)False, Because if you divide 50 by 2 to get 25 you would have to divide all the student classes by 2 causing 4 to become 2 instead of 4 for every 25.

1) true, because if you take 50 students and make it a percent its 0.5 so then divided by 20 for 20% of students taking chemistry its 0.025 so thats about 20%.

2) true, because 6 are taking physics and 12 are taking health science so twice as many are taking health science. (6+6=12)

3) true, because if you do 50*3 you get 150 and if you do 6*3 you get 18. so for every 150 students you could maybe get at least 18 of students. you are taking each number and multiplying it by 3.

4) false, because if you take 50 divided by 25 you get 2 and if you take 4*2 you get 8. i took 2 because thats how many times 25 goes into 50 and your total is 50 students so out of 25 itd be 2 and so there saying you could get 4 out of that but you really cant because 4*2 is 8.

1)the answer is true because 10 divided by 50 is .2 which is 20%

2)The answer is true because12 divided by 2 is 6 and that is half of 12

3)the answer is true because 50 multipled by 3 is 150 and 6 multipled by 3 is 18… So every 150 at least 18 are taking physics.

4)the answer is 4 because half of 50 is 25 so it would be 2 students take earth science, for every 25 students.

1) the answer is true because 10 divided by 50 is .2 which is 20%.

2) True because 6 are taking physics and 12 are taking health science. 6 times 2 equals 12 (6*2=12).

3) True because 50*3=150 and 6*3=18.

4) False because for every 50 students 4 are taking Earth Science. So for every 25 students about 2 would will take Earth Science.

1) True, 10 is 20% of 50

2) True, 6 is half of 12

3) False, 50 times 3 is 150, whereas 4 times 3 is not 18

4) False, for every 25 kids, 2 are taking earth science

1) False, because 50 divided by 10 is 5 and 5 times 20 100 not 50

2) True, because 6 times 2 is twelve which is the number of people in Health Science 6 are in Physics

3) True, because 50 times 3 is 150 you have to do the same thing to 6 and 6 times is 18

4) False, because for every 50 there are 4 people in Earth Science so for there to be 4 for every 25 then there would have to be 100 people

(1) true:10 out of 50 is 20% (2)true:12/6 =2 which is .5 of 12

(3)true:6*3=18 and 150 is 3 of the data charts

(4)false:25 is half of 50 so there would be 2 students in Earth

Science.

FINAL ANSWER!!!!!!!!!!

1. True

2.false

3. True

4. False

# 1 .Is true because you can divide 50 by 20 and you get 10.

#2. Is true because 6 times 2 equals 12 which is twice as many people doing health science then instead of physics .

#3.Is true because the 50 are doing physics.

#4.Is false because it’s not every 25 people i think it every 50 people.

1 true because if you add the numbers altogether you get fifty and fifty x 2 = 100 and 10% x 2 =20%

2 true because health science has 12 and physics has six and 12 divided my 6=6

3 true because students took the survey and 6 are taking physics 50 x3=150 and 6 x 3 =18

4 false for every 25 students 2 are taking earth science

1.)True: Cause 10 students is 20% of the class…

2.)True: Cause there are 12 students in Health Science and 1/2 of 12= 6.

3.)True: There is a total of 50 students and for there to be 150 you have to multiply by 3; Then you multiply the amount of students taking Physics which is 6; Last multiply 6 by 3=18.

4.)False: Cause the total number of students is 50 and there are 4 taking Earth Science…for 25 students it would be 2 students and not 4 so this is wrong.

number 1 is true because if you get 50 and turn it to percent you get 0.5 so then divide it by 20 it turns to 20 percent

for question 1 it is false because 10 out of 50 is 5.

for question 2 it is true because 2 times 6 is 12.

for qwestion3 it is true because there are 3 sets of 50 in 150 so 3 sets of 6 would be 18.

for number 4 it would be no because out of 50 is 4.

i think the answers are

1.true

2.true

3.true

4.faulse

on the frist one if yo take 50 student then make it to 0.5 and divied by 20 yu will get 20%.

students thant are taking physics are 6 and the ones that are taking health sceinece are 12 so 6+6=12.i

if you take 50(3) you will get 15 and if you do 6(3) you will get18

if yu get 50/2 you will get 10

1) True: If 15 students were taking chemistry that would be 25% so 10 students would be 20%.

2)True:6 is half of 12

3)True: 6(3) is 18 and 50(3) is 150

4)False: There are 4 when there are 50 students so if 25 is half of 50 then I would predict 2 students taking Earth Science.

false, I am guessing because I don’t know how to solve it.

true, because there are 6 students taking physics. 6*2=12. 12 students are talking health science.

false, because if you do the math (that’s below) the answer is 27 not 18.

false, because there are all ready 4 taking earth science.

x/150 18/100

100*x 150*18

100x(divided)100 2700(divided)100

x=27

1)this is true,cause 20 percent of 50 is 10 percent out of all the students

2)I think its true, cause six doubled is twelve

3)I think this is true cause if you times all 50 (students) by 3 the answer will be 150 cause there is 6 students in physics , 6 x 3=18

4)I don’t know this one ?

1) true because 20 percent of 50 is 10

2)true bacause half of 12 is 6,and 6 people are taking physics.

3)true bacause 150 of 50 is 3 & 3 times 6 is 18

4)false because in 25 there should only be 2.

True because I multiplied 50 and .20 and got 10

True because .5 of 12 is 6 and there is 6 students in physics

True because if you multiply 6 by 3 (you will get 18) and then I multiplied 50 by 3 because there Are 50 students and only 6 in chemistry and both equalled the amount the question said.

False because 4 students for every 50 students EQUALS 2 students for every 25 students.

True

True

False

False

1. this is true because i multiplied 50 and .20 then i got 10.

2.this is true because i devided 12 by 1/2 and it is 6 ans there is 6 students in physics.

3. true because i multiplied 6 by 3 and got 18, then i multiplied 50 by 6 and i got what the question said.

4. false because in 25 there can only be 2.

True because I multiplied 50 by .20 and my answer was 10.

True because when you divide 12 by 6 your answer is 6.

True because 150 of 50 is 3 .And 3 times 6 is 18.

False because 4 for every 50 students is 2 for every 25 students.

1. True because 50 multiplyed by 20 and i have 10

2. true becasue 5 of 12 is 6 and there is 6 students in physics

3. true because if you multiply 6 and 3 and your answer is 18 and the multiply 50 by 3 because there are 50 students and 6 in chemistry and both are equal

4. false because 4 students for every 50 sudents is equal to 2 students for every 25

1) true 2) true because 6 students are taking physics and 12 are takinghealth science . 3) true because 6/50 students are taking physics . 4) false because 4/50 students are taking earth science and there will be 2/25 students in that class.

True because I multiplied 50 and .20 and got 10

True because .5 of 12 is 6 and there is 6 students in physics

True because if you multiply 6 by 3 (you will get 18) and then I multiplied 50 by 3 because there Are 50 students and only 6 in chemistry and both equalled the amount the question said.

False because 4 students for every 50 students EQUALS 2 students for every 25 students.

false for number 1 because only 10% of it not 20%

true for 2 because 6+6= 12

true for 3 because its the most

true for 4 because its the least
