Question

Faris's gas tank is 1/10 full. After he buys 24 liters of gas, it is 2/5 full. How many liters can Faris's tank hold?

Answer 1

80 liters

Explanation:

24 liters is the difference between 2/5 full and 1/5 full.

Let x = number of liters in full tank.

2/5 x - 1/10 x = 24

4/10 x - 1/10 x = 24

3/10 x = 24

1/10 x = 8

x = 80

Answer: 80 liters
