Question

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

1 3/4 cups of cheese

2/3 cups of milk

2 1/2 cups of pasta

Answer 1

4 3/8 cups of cheese
1 2/3 cups of milk
6 1/4 cups of pasta

Divided each number but four and multiplied my answer by 10

Answer 2

Since you are making 10/4 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
