Question #972fd

Answer 1

`20.0%`

Explanation:

`20%` only has `1` significant digit (the `0` in the second digit is not a significant digit).

To make that `0` significant, you can add a decimal place: `20.%`. However, we are still one significant figure short.

We just need to append a `0` after the decimal place (which will be a significant digit) to get `20.0%`.
