How to work it out

  1. Turn the percentage into a decimal: 19 ÷ 100 = 0.19
  2. Multiply: 0.19 × 90 = 17.1
  3. Check: Work backwards: 17.1 ÷ 90 × 100 = 19%.

Another method. As a proportion of part to whole: 19/100 = part/90, so part = 19 × 90 ÷ 100 = 17.1. Both methods always give the same answer.

In a spreadsheet: =19%*90. 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

17.1 is the 19% share of 90. The remaining 81% is 72.9, and the two parts add back up to 90.

Discounts: 19% off an item priced $90 saves $17.1, so you pay $72.9.

Adding and taking away 19%

Increasing 90 by 19% gives 107.1 and decreasing it by 19% gives 72.9. These do not cancel out: raising 90 by 19% and then lowering the result by 19% ends at 86.751, because the second 19% is taken of a bigger number.
