Sorry but stuck on stupid on this one.
If I have a random number – let’s say 545 and I reduce it by 20%. It’s reduced by 109 making it 436.
But if I want to increase it back to 545 I have to add 25%
Edit: Ahhhh Thank you all for this! Makes perfect sense now!

If you multiply something by 4/5 (80%), you have to multiply it by 5/4 (125%) to get the original value back.
