Question

7

Abdul's gas tank is
1
3
full. After he buys 12 gallons of gas, it is
full. How many gallons can Abdul's tank hold?
9

Answer 1

27

Explanation:

Let T be the capacity of the tank.

Since the tank was 1/3 full and ends up 7/9 full.

`(7)/(9)`T -
`(1)/(3)`T = 12

Simplifying the left side of the equation, tells us how much 12 gallons fills.

`(4)/(9)`T = 12

Now we solve for T:

T = 12*9/4

T = 27
