Step-by-step explanation:

Answer 2

So, if the ratio of girls to boys is 3:2 (imagine this: 3 and 2 groups of equal number, that's 5 groups and then each group will have 40/5=8 people), so there are 3*8=24 boys and 2*8=16 girls.

1 : 3 : 2 : 2
this ratio means dividing the girls into 1+3+2+2=8 groups of 2, so the actual numbers are:
2:6:4:4
 
4 : 3 : 1 this ratio means dividing the boys into 4+3+1=8 groups of 3, so the actual numbers are:
12:9:1

A.we know the actual numbers: 4 girls and 12 boys, so the ratio is 4:12, or simplifying: 1:3

B: look here: 2:6:4:4
