How to work it out
- Turn the percentage into a decimal: 39 ÷ 100 = 0.39
- Multiply: 0.39 × 45 = 17.55
- Check: Work backwards: 17.55 ÷ 45 × 100 = 39%.
Another method. As a proportion of part to whole: 39/100 = part/45, so part = 39 × 45 ÷ 100 = 17.55. Both methods always give the same answer.
In a spreadsheet: =39%*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 39%
Increasing 45 by 39% gives 62.55 and decreasing it by 39% gives 27.45. These do not cancel out: raising 45 by 39% and then lowering the result by 39% ends at 38.1555, because the second 39% is taken of a bigger number.
