There are 15 boys and 45 girls competing in a race. What is the ratio of girls to boys in the race , lowest terms ?
Ivanshal [37]
<h3>Answer =  3:1</h3>

==========================================

Work Shown

45 girls : 15 boys

45/15 girls : 15/15 boys .... divide both parts by 15

3 girls : 1 boy

This tells us there are three times as many girls as there are boys.

We write this as the ratio 3 : 1. The order of the terms is important. We cannot say 1:3 since that would imply there are more boys than girls, but it's the other way around.

x = 4

So DG = 5 + 4 + 3 which is 12
