Question

Two different schools (A and B) have the same number of pupils. The ratio of the boys in school A and the boys in school B is 2:1 and the ratio of the girls in school A and the girls in school B is 4:5. Find the ratio of the boys in school A to the girls in school A.

Answer 1

Answer: a/b

Explanation:

Answer 2

A to B = A/B

This means A = 2 and B = 1 in terms of the boys.

A to B = A/B

This means A = 4 and B = 5 in terms of girls.

Let R = ratio of boys in school A to the girls in school A.

R = A to A

R = A/A

R = 2/4

R = 1/2
