Question

How do write in simplest form given `-32.4div21.3`?

Answer 1

`-108-:71`

Explanation:

Here's how I did it :
`-32.4-:21.3` is the same thing as `-32.4/21.3`
Multiply by 10 :

`-(32.4xx10)/(21.3xx10)=-324/213`

Notice that they have a common factor which is 3:

`-324/213=-(108xx3)/(71xx3)`

Simplify and you'll get : `-108/71`

71 and 108 have no common factor so that's the simplest form.
