A rain water barrel 2/3 full. After 60litres were used in the barrel it was 1/9. How much water will the barrel hold if fully

Answer 1

Hi Touray, let x represent the amount of water in the barrel when it is full. To solve this question, solve the following equation:

2 / 3 * x - 60 = 1 / 9 * x

Collect terms:

2 / 3 * x - 1 / 9 * x = 60

Common denominator is 9:

6 / 9 * x - 1 / 9 * x = 60

5 / 9 * x = 60

x = 60 * (9 / 5)

x = 108

The barrel when full contains 108 liters.
