Question

During a rain shower, Jeanette collects 42

1/2
gallons of water in a rain barrel outside her home. She uses 1
1/4
gallons to water plants inside her house. Then, she uses
1/2 of the remaining water to wash a load of dirty laundry. How many gallons of water does Jeanette use to wash her laundry?

Answer 1

Answer: 20 5/8 gallons of water

Step-by-step explanation: First, we have to do the 42 1/2 (total) minus 1 1/4, which is 41 1/4. Half (1/2) of 41 1/4 is 20 5/8. So Jeanette used 20 5/8 gallons to wash her laundry.
