Answer:
30 g butter, 15 g sugar, and 45 g flour
Step-by-step 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.
