Question

What percent of $90 is $9?

Answer 1

`10%`

Explanation:

If `$90` is `100%`, then `$9` would be `10%`.

This is because:

`$90` is `100%` because this is the total.
`$9` is `x%`

You can see that the `$9` is a tenth of the total value of `$90`, i.e:

`($90)/($10)=$9`

Therefore, the fraction of `1/10` is equivalent to `0.1` and this is the decimal representation of the percentage of `10%`.

Answer 2

`10%`

Explanation:

To determine what percentage one quantity is of another you can use the method:

`"fraction" xx 100%`

IN this case:

`9/90 xx100%`

`=1/10 xx100%`

`=10%`
