Question

Ryan’s gas tank is 1/2 full. After he buys 6 gallons of gas, it is 7/10 full. How many gallons can the gas tank hold

Answer 1

Answer: 30 gallons. If it’s half way full (5/10) and it goes up 2/10 with 6 gallons, that means every 1/10 is 3 gallons and 3•10= 30

Answer 2

30 gallons

Explanation:

1/2 + 2/10 = 7/10

2/10 = 6 gallons

2/10 divided by 2 = 1/10

1/10 = 3 gallons

3 gallons x 10 = 30 gallons on 10/10 tank full
