Example 1.
Let's say you had 100. You then subtracted 20%. 100 - 20% = 100 - 20 = 80.
To get back to your original amount (the new amount is 80% of the original) you would divide the new number by 80 and multiply by 100.
80/80 * 100 = 100.
Example 2
50 reduced by 10% = 50 - 5 = 45
If 45 is therefore 90% of the original then 100% = 45/90 * 100 = 50
