How to work it out
- Turn the percentage into a decimal: 55 ÷ 100 = 0.55
- Multiply: 0.55 × 45 = 24.75
- Check: Work backwards: 24.75 ÷ 45 × 100 = 55%.
Another method. As a proportion of part to whole: 55/100 = part/45, so part = 55 × 45 ÷ 100 = 24.75. Both methods always give the same answer.
In a spreadsheet: =55%*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

Adding and taking away 55%
Increasing 45 by 55% gives 69.75 and decreasing it by 55% gives 20.25. These do not cancel out: raising 45 by 55% and then lowering the result by 55% ends at 31.3875, because the second 55% is taken of a bigger number.
