Question

A recipe calls for 31​ cup of flour to make 5 dinner rolls. How many cups of flour are needed to make 36 dinner rolls using the same recipe?

Answer 1

To find out how many cups of flour are needed to make 36 dinner rolls using the same recipe, we can set up a proportion:

31 cups of flour = 5 dinner rolls
x cups of flour = 36 dinner rolls

We can cross multiply to solve for x:

31 * 36 = 5 * x
1116 = 5x
x = 223.2

Therefore, 223.2 cups of flour are needed to make 36 dinner rolls using the same recipe.
