How to work it out
- Turn the percentage into a decimal: 23 ÷ 100 = 0.23
- Multiply: 0.23 × 99 = 22.77
- Check: Work backwards: 22.77 ÷ 99 × 100 = 23%.
Another method. As a proportion of part to whole: 23/100 = part/99, so part = 23 × 99 ÷ 100 = 22.77. Both methods always give the same answer.
In a spreadsheet: =23%*99. Forgetting to divide the percentage by 100 makes the answer 100 times too big. Note that x% of y always equals y% of x.
What the result means
22.77 is the 23% share of 99. The remaining 77% is 76.23, and the two parts add back up to 99.

Adding and taking away 23%
Increasing 99 by 23% gives 121.77 and decreasing it by 23% gives 76.23. These do not cancel out: raising 99 by 23% and then lowering the result by 23% ends at 93.7629, because the second 23% is taken of a bigger number.
