Step 1: Divide the number of ounces by the number of ounces in a cup. To do this, divide 21 by 8.
- 21 ÷ 8 = 2.625

To round 2.625 to the nearest whole number, you would round down to 2.625 is closer to 2.6, but for the sake of this example, we'll round down to 2.625 to 2.6 cups is not the same as 2.625 cups, we will round down to 2 cups and 8 oz. We will round down to 2 cups and 8 oz is equal to 2.625 cups, let's round down to 2 cups and 3 oz is equal to 2.375 cups, neither of which is the same as 2.625 cups, so we will round down to 2 cups and 5 oz is equal to 2.625 cups, let's round down to 2 cups and 5 oz.
Step 2: Write the result as a decimal or a mixed number. In this case, you can express 2.625 cups as 2 cups and 5 oz.
