How to work it out
- Turn the percentage into a decimal: 99 ÷ 100 = 0.99
- Multiply: 0.99 × 45 = 44.55
- Check: Work backwards: 44.55 ÷ 45 × 100 = 99%.
Another method. As a proportion of part to whole: 99/100 = part/45, so part = 99 × 45 ÷ 100 = 44.55. Both methods always give the same answer.
In a spreadsheet: =99%*45. 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
44.55 is the 99% share of 45. The remaining 1% is 0.45, and the two parts add back up to 45.

Adding and taking away 99%
Increasing 45 by 99% gives 89.55 and decreasing it by 99% gives 0.45. These do not cancel out: raising 45 by 99% and then lowering the result by 99% ends at 0.8955, because the second 99% is taken of a bigger number.
