Answer 2

I just need somone to explain to me on how to get the answer, I have the answer but I don't know how to do the problem.

Answer 3

This is easy.
Basically, all you have to do is split the amount of juniors into 7 parts. (3:4, 3+4 =7)
238 ÷ 7 = 34
Number of girls: 3/7, so 34 * 3 = 102 girls
Boys: 4/7, 34*4 = 136
Think of it like fractions

Answer 4

Answer 5

Answer 6

Answer 7

Answer 8

Like I said. Think of it like fractions. Ratios are just another way of expressing fractions.
3:4, 3 girls for every 4 boys. If you have 7 people, 3 are girls, 4 are boys. 3/7 girls, 4/7 boys
If you have 238 people, and 3/7 are girls, and 4/7 are boys....what do you do to find how many boys and how many girls?
