Question

How do write in simplest form given `1/2-1/3`?

Answer 1

We first have to make the denominators equal before anything else.

Explanation:

We can multiply each fraction by `1` without consequence, where the `1` is written as `3/3` and `2/2` respectively:
`=1/2*3/3-1/3*2/2`

`=(1*3)/(2*3)-(1*2)/(3*2)`

`=3/6-2/6=(3-2)/6=1/6`
