Question

use a proportion to convert the measurement. 9 quarts = liters

Explanation:

Step1: Recall the conversion factor

We know that 1 quart is approximately equal to 0.9464 liters. So we set up a proportion: $\frac{1\ \text{quart}}{0.9464\ \text{liters}}=\frac{9\ \text{quarts}}{x\ \text{liters}}$.

Step2: Solve the proportion

Cross - multiply the proportion: $1\times x = 0.9464\times9$. Then calculate $0.9464\times9 = 8.5176$.

Answer:

8.5176 (or approximately 8.52 depending on the required precision)
