How to work it out
- Turn the percentage into a decimal: 45 ÷ 100 = 0.45
- Multiply: 0.45 × 19 = 8.55
- Check: Work backwards: 8.55 ÷ 19 × 100 = 45%.
Another method. As a proportion of part to whole: 45/100 = part/19, so part = 45 × 19 ÷ 100 = 8.55. Both methods always give the same answer.
In a spreadsheet: =45%*19. 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
8.55 is the 45% share of 19. The remaining 55% is 10.45, and the two parts add back up to 19.

Adding and taking away 45%
Increasing 19 by 45% gives 27.55 and decreasing it by 45% gives 10.45. These do not cancel out: raising 19 by 45% and then lowering the result by 45% ends at 15.1525, because the second 45% is taken of a bigger number.
