Question

The ratio of boys to girls in an after school recycling club is 4:7. If there are 20 boys in the recycling club, how many girls are there?

Answer 1

There are 35 girls in the recycling club

Explanation:

4 boys : 7 girls

20 boys : x girls

In order to get to 20, you have to multiply 4 by 5, so multiply 5 to 7 for the girls.

7(5) = 35

There are 35 girls
