Answer:
Step-by-step explanation:
1. What fractional part of the brown sugar needed does she have?
The recipe says that you need 1 1/2 cups of brown sugar and she has 1 1/8, so the fraction would be
(1 1/8) / (1 1/2) = 3/4 of the total
2. What method could be used to scale down the other ingredients of the recipe in order to make it with the limited amount of brown sugar?
She has to multiply each ingridient by 3/4
3.
2 * 3/4 = 1 1/2 cups butter
2 1/4 * 3/4 = 1 11/16 cups flour
2 * 3/4 = 1 1/2 eggs
1 * 3/4 = 3/4 tsp salt
1 1/4 * 3/4 = 15/16 tsp baking soda
1 * 3/4 = 3/4 tsp vanilla
1/4 * 3/4 = 3/16 cup sugar
1 1/8 cup brown sugar
10 * 3/4 = 7 1/2 ounces choc chips
How many cookies will the scaled down recipe make?
24 * 3/4 = 18 cookies
