the ratio of the amount of water the Chen family used on a sunday for bathing to the amount of water they used for washing laundry to the amount of water they used for washing their car was 9:7:1. They used 144L of water for bathing. How much water did the Chen Family use for washing laundry
Let's assume that the amount of water used for washing laundry is x.
According to the given ratio, the amount of water used for bathing is 9x and the amount of water used for washing the car is x/7.
Given that the amount of water used for bathing is 144L:
9x = 144
x = 144/9
x = <<16=16>>16L
Therefore, the Chen Family used 16L of water for washing laundry.
