A recipe for cookies requires 2/3 cups of butter. Rama wants to make 3/4 of the recipe. How many cups of butter should Rama use to make the cookies.

3/4 * 2/3 = 6/12 = 1/2

To find out how many cups of butter Rama should use to make the cookies, we need to calculate 3/4 of 2/3 cups of butter.

First, let's find 3/4 of 2/3 cups:

(3/4) * (2/3) = (3 * 2) / (4 * 3) = 6/12 = 1/2.

Therefore, Rama should use 1/2 cup of butter to make the cookies.
