When Mrs. Stewart makes pie dough, she uses 2/3 cup of shortening for every 2 1/2 cups of flour which proportion could be used to find the amount of flour, x Mrs. Stewart needs when she uses 5 cups of shortening

(2/3) / (2 1/2) = 5 / x

good job

To find the amount of flour, x, that Mrs. Stewart needs when she uses 5 cups of shortening, we can set up a proportion using the given information.

The proportion is: (amount of shortening) / (amount of flour) = (amount of shortening) / (amount of flour)

In this case, the given information tells us that Mrs. Stewart uses 2/3 cup of shortening for every 2 1/2 cups of flour. So we can set up the following proportion:

(2/3) / (2 1/2) = 5 / x

To solve for x, we can cross-multiply and then solve for x:

(2/3) * x = (5 * 2 1/2)

First, let's convert the mixed number 2 1/2 to an improper fraction:

2 1/2 = 5/2

Now we can rewrite the equation:

(2/3) * x = (5 * 5/2)

To simplify the right side of the equation:

(2/3) * x = (25/2)

To get x by itself, we can multiply both sides of the equation by the reciprocal of (2/3):

x = (25/2) * (3/2)

x = (75/4)

So Mrs. Stewart needs 75/4 cups of flour when she uses 5 cups of shortening.
