Question

My recipe calls for 2/3 cups of white flour and 2 1/5 cups of whole wheat flour. How much flour do I need total for my recipe?

Answer 1

Add the fractions: 2/3 + 2 2/5 = 2/3 + 12/5 = 10/15 + 36/15 = 46/15 cups.

So you need 46/15 cups = 3 1/15 cups ≈ 3.07 cups total.

(If you prefer household measures: 3 cups + 1/15 cup ≈ 3 cups + 3.2 teaspoons ≈ 3 cups + 1 tablespoon + 0.2 teaspoon.)
