Answer
21.9 L (rounded)
Work Step by Step
We’re changing from a U.S capacity unit to a metric capacity unit. In the “U.S. to Metric Units” side of the table, you see that 1 quart = 0.95 liter. Use Unit fraction (0.95 L)/(1 qt)
Multiply by the unit fraction that allows you to divide out qt (that is, qt is in the denominator).
23 qt *(0.95 L)/(1 qt) = 21.85 L = 21.9(rounded)
