The recipe below shows the amount of each ingredient required to make four servings of pasta. Base d on this information, determine the amount of each ingredient needed to make 10 servings.

Question

1 3/4 cups, 2/3 cups milk and 2 1/2 cups pasta

Answer 1

Since you are making 10/4 or 2 1/2 times the original number of servings, you simply multiply the amount of each ingredient by 2 1/2 or 5/2:

1 3/4 cups of milk = 7/4 cups, so 7/4 * 5/2 = (7*5)/(4*2) = 35/8 = 4 3/8 cups of milk

Compute the amount of the other 2 ingredients similarly.
