Question

Susan gave 1/3 of a pizza to her brother. She gave 1/2 of what was left to her mother. Susan ate the rest herself. What fraction of the pizza did Susan eat?

Answer 1

`(1)/(3)`

Explanation:

After Susan gave away
`(1)/(3)` of the pizza,
`(2)/(3)` remains. And now of that
`(2)/(3)` of the pizza she gave away
`(1)/(2)`. Multiply those two fractions to get
`(1)/(3)`.
