Answer:

15

Step-by-step explanation:

Firstly, divide the number of girls by the ratio of girls:

9 ÷ 3 = 3

Now multiply the number of boys in the ratio by 3:

5* 3 = 15

So there are 15 boys.

Answer:

15 boys

Step-by-step explanation:

3:5 is your original ratio so..

3*3=9 (girls)

5*3=15(boys)

Also, a small rule to follow with ratios is if for example if you multiply something by 2 then you multiply the other ratio by 2 as well!
