20.0%
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%#.
