How to work it out
- Turn the percentage into a decimal: 19 ÷ 100 = 0.19
- Multiply: 0.19 × 45 = 8.55
- Check: Work backwards: 8.55 ÷ 45 × 100 = 19%.
Another method. As a proportion of part to whole: 19/100 = part/45, so part = 19 × 45 ÷ 100 = 8.55. Both methods always give the same answer.
In a spreadsheet: =19%*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 19%
Increasing 45 by 19% gives 53.55 and decreasing it by 19% gives 36.45. These do not cancel out: raising 45 by 19% and then lowering the result by 19% ends at 43.3755, because the second 19% is taken of a bigger number.
