Question

Nancy ate 1/3 of a pizza and gabe ate 1/4 of the pizza. how much of the whole pizza is left.

Answer 1

1/3 = 4/12
1/4 = 3/12
7/12 they ate
12-7=5
5/12 is left

Answer 2

`(5)/(12)`

Explanation:

Let the total part of the pizza be x

Nancy ate part of pizza=
`(1)/(3)`x

Gabe ate part of pizza=
`(1)/(4)`x

Total part of the pizza is eaten =
`(1)/(3)`x +
`(1)/(4)`x

Total part of the pizza is eaten=
`(3x+4x)/(12)`

Total part of the pizza is eaten=
`(7x)/(12)`

Part of the pizza is left= x -
`(7x)/(12)`

Part of the pizza is left=
`(12x-7x)/(12)`

Part of the pizza is left=
`(5x)/(12)`

Hence, the correct answer is
`(5)/(12)`
