Question

What is 0.3% as a fraction?

Answer 1

`3/1000`

Explanation:

A percentage is actually just a part out of 100. So for example, 10% is the same as 10 out of a 100 or `10/100` which simplifies to `1/10`.

In this case we see `0.3%` which is like saying `0.3/100`. Of course we do not want decimals in the numerator (the same way we wouldn't want a fraction in the numerator of a fraction). So to fix this we could multiply by `10/10` (which is to say `1`) to make `0.3` into a whole number.

`0.3/100 * 10/10 = 3/1000` and cannot be simplified.
