Question

How do you simplify `1/7 + 2/3`?

Answer 1

`17/21`

Explanation:

`1/7 + 2/3 = 3/21+14/21=17/21`

Answer 2

`17/21`

Explanation:

first find the lowest common denominator, in this case it would be 21 (7 x 3). 7 and 3 have no lower possibilities.

what we do to the bottom we must do to the top so since we multiplied the 7 in `1/7` by 3, we have to do that to the 1 as well. Same goes for the `2/3` - the 2 needs to be multiplied by 7.

`1/7 + 2/3`

`3/21 + 14/21`

`17/21`
