    You can do this several ways. 1. Notice that 9 cups is 1.5 times 6 cups. That means you need 1.5 * 1/3 1.5 ^ 1/3 = 1/2 Answer is 1/2 cup 2. Set up a proportion. 6 serving is to 1/3 cup as 9 servings is to x cups 6 : 1/3 = 9 : x \(\dfrac{6}{\frac{1}{3}} = \dfrac{9}{x} \) \(6x = \ \times \dfrac{1}{3} \) \(6x = 3\) \(x = \dfrac{1}{2} \) Once again, we have an answer of 1/2 cup.
