If a recipe requires 3 cups of flour to make 12 cookies, how many cups are needed for 36 cookies?

1. 6 cups

2. 9 cups

3. 12 cups

4. 18 cups

The correct answer is: 9 cups

To determine how many cups of flour are needed to make 36 cookies, we start by identifying the relationship between the amount of flour and the number of cookies in the original recipe. The recipe states that 3 cups of flour yield 12 cookies. To find out how much flour is needed for 36 cookies, we can first set up a proportion based on the initial recipe. If 12 cookies require 3 cups of flour, we can express the amount of flour needed per cookie: \[ \text{Flour per cookie} = \frac{3 \text{ cups}}{12 \text{ cookies}} = \frac{1}{4} \text{ cup per cookie} \] Now, to find out how much flour is needed for 36 cookies, we multiply the number of cookies by the amount of flour needed per cookie: \[ \text{Total flour for 36 cookies} = 36 \text{ cookies} \times \frac{1}{4} \text{ cup per cookie} = 9 \text{ cups} \] Thus, 9 cups of flour are required to make 36 cookies. This confirms that the correct answer is 9 cups, as it directly scales the
