Question

The ratio of boys to girls on a swimming team is 4 to 3. If there are 20 boys, how many girls are on the swimming team?

Answer 1

15 girls

Explanation:

x = # of girls on the swimming team

Use ratios

(4 boys / 3 girls) = (20 boys / x)

Then cross multiply

4 x = 20 * 3

4x = 60, then divide each side by 4

x = 15
