Answer 2

(B)72 fluid ounces

Explanation:

To convert cups to fluid ounces, Sari wrote the equivalent ratios.

`\frac{8 \text{ fluid ounces}}{1\text{ cup}} =\frac{\text{? fluid ounces}}{9\text{ cups}}`

Let the question mark be represented by x.

We then have:

`\frac{8 \text{ fluid ounces}}{1\text{ cup}} =\frac{\text{x fluid ounces}}{9\text{ cups}}\\$Cross multiply\\x * 1 = 8 * 9\\x=72$ fluid ounces`

We conclude that there are 72 fluid ounces in 9 cups.
