Question

How do you evaluate `3/9 + 4/5`?

Answer 1

`1 2/15`

Explanation:

To add fractions the denominators must be the same. `3/9` can be simplified to `1/3`, so the sum becomes `1/3 + 4/5`. The lowest common denominator for `3` and `5` is `15`, so we multiply `1/3` by `5/5`, resulting in `5/15` and we multiply `4/5` by `3/3`, resulting in `12/15`. Now we can add the two fractions:

`5/15 + 12/15 = 17/15 = 1 2/15`
