How to work it out
- Turn the percentage into a decimal: 55 ÷ 100 = 0.55
- Multiply: 0.55 × 99 = 54.45
- Check: Work backwards: 54.45 ÷ 99 × 100 = 55%.
Another method. As a proportion of part to whole: 55/100 = part/99, so part = 55 × 99 ÷ 100 = 54.45. Both methods always give the same answer.
In a spreadsheet: =55%*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
54.45 is the 55% share of 99. The remaining 45% is 44.55, and the two parts add back up to 99.

Adding and taking away 55%
Increasing 99 by 55% gives 153.45 and decreasing it by 55% gives 44.55. These do not cancel out: raising 99 by 55% and then lowering the result by 55% ends at 69.0525, because the second 55% is taken of a bigger number.
