Question

I eat 1/4 of a pizza and my friend eats 1/3. How
much is left?

Answer 1

Explanation:

Add 1/4 and 1/3.

`(1 * 3)/(4 *3) =(3)/(12)`

`(1 * 4)/(3 * 4) =(4)/(12)`

`(4)/(12) +(3)/(12) =(7)/(12)`

Subtract 7/12 from the whole (1) or (12/12):

`(12)/(12) -(7)/(12) =(5)/(12)`

`(5)/(12)` of the pizza is left.
