Question

Ms. Mather filled 8 3/4 gallons of gas in her car's fuel tank. The car used up 3 1/2 gallons when she visited a friend in a neighboring town. How many gallons of gas are left in Ms. Mather's fuel tank?

Answer 1

5 1/4 gallons are left... correct

Answer 2

Answer:
`5(1)/(4)` gallons are left

Explanation:

convert to mixed number...

`8(3)/(4) = (35)/(4)`

`3 (1)/(2) = (7)/(2)` or
`(14)/(4)`

`(35)/(4) -(14)/(4)=(21)/(4)`

`(21)/(4) =5(1)/(4)`

therefore,
`5(1)/(4)` gallons are left in Ms. Mather's fuel tank
