Question

This recipe makes 20 shortbread fingers.

Rose follows this recipe, but only wants to make 5 fingers.
How much of each ingredient does she need?

Recipe: Makes 20
120 g butter
60 g sugar
180 g flour

Answer 1

Explanation:

120 divided by 4=30g butter

60 divided by 4=15g sugar

180 divided by 4=45g flour

Answer 2

30 g butter, 15 g sugar, and 45 g flour

Explanation:

Since each ingredient (120 grams butter, 60 grams sugar, 180 grams flour) makes 20 shortbread fingers, but we only want 5, which is 1/4 of 20, we need to cut everything down by a factor of 4 - in other words, divide them all by 4 to get the amount of each we need:

- 120 g butter: 120 ÷ 4 = 30 g butter

- 60 g sugar: 60 ÷ 4 = 15 g sugar

- 180 g flour: 180 ÷ 4 = 45 g flour

Thus, the ingredient amounts she needs are: 30 g butter, 15 g sugar, and 45 g flour.
