Answer:

#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%#.
