Recipe Fractions

Question

If a recipe takes 1 1/2 cups of milk for 4 servings, how much milk is needed for 6 servings?

Answer 1

Let x denote the quantity of milk (cups) required for 6 servings. You need to create a ratio (quantity of milk per serving) as follows:

1.5 cups/4 = x/6 --> x = 6*(1.5/4) = 9/4 = 2 + 1/4 cups of milk is required to make 6 servings.
