Stan's recipe for sugar cookies serves 5 people. He wants to make enough cookies for 10 people.

If his recipe calls for 1 1/2 cups of butter, how much will he need if he doubles his recipe?

(1 1/2) * 2 = 3

Please tell Stan to check his recipe. 1 1/2 cups is too much butter for 5 people.

6/2

Ada has 5 pints of Apple.she need 3/2 pints to make a batch of Apple ice cream. How many batches of Apple ice cream can Ada make?

To find out how much butter Stan will need if he doubles his recipe, we can use a proportion.

Let's first determine the ratio of butter to the number of people in the original recipe. Stan's recipe serves 5 people and calls for 1 1/2 cups of butter. So the ratio of butter to people is 1 1/2 cups / 5 people.

To find out how much butter he will need for 10 people, we can set up a proportion using the above ratio:

1 1/2 cups / 5 people = X cups / 10 people

To solve for X (the amount of butter needed for 10 people), we can cross-multiply and solve for X:

5 * X cups = 1 1/2 cups * 10 people

5X = 15 cups * people

X = 15 cups * people / 5

X = 3 cups

Therefore, if Stan doubles his recipe to serve 10 people, he will need 3 cups of butter.
