To make soup, Philip mixes 3 3/8 cups of broth with 2 1/4 cups of water. How many cups of liquid does he use

To find the total amount of liquid Philip uses, we need to add the amounts of broth and water.

3 3/8 cups + 2 1/4 cups.

First, let's add the whole numbers: 3 + 2 = 5.

Next, we add the fractions: 3/8 + 1/4.

To add fractions, we need a common denominator. In this case, the smallest common denominator is 8.

To convert 1/4 to have a denominator of 8, we multiply the numerator and denominator by 2: (1/4) * (2/2) = 2/8.

Now, we can add the fractions: 3/8 + 2/8 = 5/8.

Therefore, the total amount of liquid Philip uses is 5 cups 5/8 cups or 5 5/8 cups. Answer: \boxed{5 \frac{5}{8}}.
