ten

twelve

fifteen

eighteen

Answer 1

You need to figure out first how many friends chose song A. Then subtract that number from the total number to get the remaining number of friends. Let's start there. Can you figure out how many friends chose song A?

Answer 2

4

Answer 3

No, I'm sorry that's not correct. If there are 30 total people and 2/5 chose song A, how many people chose song A? Can you come up with an expression for that?

Answer 4

is it 8 people

Answer 5

30(2/5) = 12 that chose A. Do the arithmetic. Stop guessing.

Answer 6

I dont know the arithmetic im stupid :/

Answer 7

Ok, here's your set up for the number of people who chose song A: \[\frac{ 2 }{ 5}*30\]You an reduce between the 5 and the 30 and get 2 * 6 = 12. 12 friends chose song A. If 12 chose song A, how many friends were left to choose B or C?

Answer 8

Please don't say you're stupid. That is not true at all. Being stupid would be not understanding it and then not caring.

Answer 9

I think its B

Answer 10

No, B is not correct. 12 chose A. That leaves 30 - 12 = 18 friends. They tell you that 1/6 of the remaining 18 chose B. 1/6 * 18 = 3. The first 12 chose A then 3 chose B, so that accounts for 15 friends. All the rest of the 30 chose C. If 15 chose A or B, then how many chose C?

Answer 11

Can you get it?

Answer 12

is the answer 12

Answer 13

No, it's 15. That is choice C or 3 down from the top.

Answer 14
