Answer:
15 boys
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!
15
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.
Hope this helps!
