Question

7) The ratio of boys to girls in a class is 2:3. If there are 18 boys in the class, how

many girls are in that class?

Answer 1

27

Explanation:

Boys to girls is 2:3

and there are 18 boys so that means the 2 in 2:3 is actually 18

and 2 x 9 = 18 , so you would need to also multiply 3 by 9.

3 x 9 = 27

18:27

there are 27 girls
