Answer 1

5.2 g

Explanation:

You want the grams of protein in 100 g of yoghurt A if it provides 6.5 g of protein in 125 g of yoghurt.

Proportion

The amount of protein is proportional to the amount of yoghurt, so we have ...

6.5/125 = p/100

p = 100(6.5/125) = 6.5/1.25 = 5.2

100 g of yoghurt A provides 5.2 g of protein.
