Question

At the parents evening the ratio of mums to dads was 3:2. Out of 500 appointments how many were with mums?

Answer 1

300

Explanation:

Answer 2

300

Explanation:

Sum the parts of the ratio : 3 + 2 = 5 parts

Divide the number of appointments by 5 to find the value of one part of the ratio, that is

`(500)/(5)` = 100 ← value of 1 part of the ratio

The mums consisted of 3 parts, hence

3 × 100 = 300 ← appointments with mums
