Sasha makes breakfast using oats, currants and wheat germ in the ratio 2:1:1 by mass. If she has only 24 g of currants, how much oats does she use?

12 g

24 g

48 g

96 g

The ratio of oats:currants:wheat germ = 2:1:1. If currants are 24g and have a ratio of 1, then oats, which is 2, is 2 * 24g = 48g
