How This Works
This reverses the usual "X% of Y" calculation. Instead of finding a percentage of a known number, you know the result and what percentage it represents, and want to find the original number — handy for working backward from a discounted price, a tax-inclusive total, or a survey result.
Formula
Original Number = Result ÷ (Percent ÷ 100)
Example
If 45 is 20% of a number, that number is 225 (45 ÷ 0.20).
