Explanation:

step 1: add the ratios

1/2 + 1/4 + 1/5 = 0.95

step 2: divide each ratio by the total sum of the ratios and multiply by a 100

(1/2 ÷ 0.95) × 100 = 52.63 rounded off equals to 53

(1/4 ÷ 0.95) × 100 = 26.31 rounded off equals to 26

(1/5 ÷ 0.95) × 100 = 21.05 rounded off equals to 21

These ratios should add up to a 100

so the ratio are 53 : 26 : 21
