Question

Butter and flour are mixed in the ratio 2:3 Chris has 640 g of butter and 880 g of flour how much flour does he need?

Answer 1

Answer:

80g

Step-by-step explanation:

Let the amount of flour needed be x grams.

Then the ratio of butter and flour needed is 640/x and this ratio is equal to 2/3

So 640/x = 2/3

640×3 = 2x

1920= 2x

x = 1920/2

x=960g

Chris already has 880g of flour.

So the amount of flour he needs more is 960-880=80g
