How to work it out

  1. Turn the percentage into a decimal: 99 ÷ 100 = 0.99
  2. Multiply: 0.99 × 19 = 18.81
  3. Check: Work backwards: 18.81 ÷ 19 × 100 = 99%.

Another method. As a proportion of part to whole: 99/100 = part/19, so part = 99 × 19 ÷ 100 = 18.81. Both methods always give the same answer.

In a spreadsheet: =99%*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

18.81 is the 99% share of 19. The remaining 1% is 0.19, and the two parts add back up to 19.

Discounts: 99% off an item priced $19 saves $18.81, so you pay $0.19.

Adding and taking away 99%

Increasing 19 by 99% gives 37.81 and decreasing it by 99% gives 0.19. These do not cancel out: raising 19 by 99% and then lowering the result by 99% ends at 0.3781, because the second 99% is taken of a bigger number.
