Question

1 full tank - 1/2 tank 0- 1/3 tank leaves what?

Answer 1

To subtract fractions, all we need is a common denominator.

1×1=1 2×1=2 3×1=3
1×2=2 2×2=4 3×2=6
1×3=3 2×3=6
1×4=4
1×5=5
1×6=6

the least common denominator is 6


`(6)/(6)` = 1

`(3)/(6) = (1)/(2)`

`(2)/(6) = (1)/(3)`


`(6)/(6) - (3)/(6) - (2)/(6)`
=
`(1)/(6)`


`(1)/(6)` of the tank is left
