How to work it out
- Turn the percentage into a decimal: 18 ÷ 100 = 0.18
- Multiply: 0.18 × 19 = 3.42
- Check: Work backwards: 3.42 ÷ 19 × 100 = 18%.
Another method. As a proportion of part to whole: 18/100 = part/19, so part = 18 × 19 ÷ 100 = 3.42. Both methods always give the same answer.
In a spreadsheet: =18%*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
3.42 is the 18% share of 19. The remaining 82% is 15.58, and the two parts add back up to 19.

Adding and taking away 18%
Increasing 19 by 18% gives 22.42 and decreasing it by 18% gives 15.58. These do not cancel out: raising 19 by 18% and then lowering the result by 18% ends at 18.3844, because the second 18% is taken of a bigger number.
