1.2 gal (rounded)

#### Work Step by Step

Given, the rinse-and-hold cycle in a dishwasher uses only 4.5 L of water.
To find gallons does it use, to the nearest tenth
We’re changing from a metric capacity unit to a U.S. capacity unit. In the “Metric to U.S. Units” side of the table, you see that 1 liter = 0.26 gallon. Two unit fractions can be written using that information.(1 liter)/(0.26 gallon) Or(0.26 gallon)/(1 liter).
Multiply by the unit fraction that allows you to divide out liter (that is, liter is in the denominator).
4.5 L * (0.26 gallon)/(1 liter) = 1.17 gal = 1.2 gal (rounded)
