A recipe calls for 2 cups of flour to make 24 cookies. How many cups of flour would it take to make 39 cookies?
2 * (39 / 24)
1 cup ==> 12 cookies, so one cookie is made using 1/12 of a cup. So using this...
39 cookies are made using 39/12 cups of flour, which would be your answer.
To solve this problem, we need to find the ratio between the number of cookies and the amount of flour required.
First, let's set up a proportion. We know that 2 cups of flour make 24 cookies. Let's represent the unknown amount of flour needed for 39 cookies as "x".
So our proportion is:
2 cups of flour / 24 cookies = x cups of flour / 39 cookies
To solve this proportion, we can cross-multiply.
2 * 39 = 24 * x
78 = 24x
To find the value of x, we divide both sides of the equation by 24.
78 / 24 = x
x ≈ 3.25
Therefore, it would take approximately 3.25 cups of flour to make 39 cookies.
