Question

Deshaun's gas tank is 1/10 full. After he buys 6 gallons of gas, it is 2/5 full. How many gallons can Deshuan's tank hold?

Answer 1

Deshaun’s gas tank holds 20 gallons of gas.
6 gallons + x gallons = 40% of the tank’s capacity.
6 gallons = 30% of the tank’s capacity.
That means that 18 gallons = 90% of the tank’s capacity.
10% of the tank’s capacity = 2 gallons.
Therefore, 100% of the tank’s capacity is 20 gallons. Meaning Deshaun’s gas tank holds 20 gallons of gas.

Answer 2

20 gallons

Explanation:

2/5 = 4/10

3/10 = 6 gallons

1/10 = 6 : 3= 2 gallons

10/10 = 2 * 10 = 20 gallons
