How to work it out

  1. Turn the percentage into a decimal: 81 ÷ 100 = 0.81
  2. Multiply: 0.81 × 17 = 13.77
  3. Check: Work backwards: 13.77 ÷ 17 × 100 = 81%.

Another method. As a proportion of part to whole: 81/100 = part/17, so part = 81 × 17 ÷ 100 = 13.77. Both methods always give the same answer.

In a spreadsheet: =81%*17. 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

13.77 is the 81% share of 17. The remaining 19% is 3.23, and the two parts add back up to 17.

Discounts: 81% off an item priced $17 saves $13.77, so you pay $3.23.

Adding and taking away 81%

Increasing 17 by 81% gives 30.77 and decreasing it by 81% gives 3.23. These do not cancel out: raising 17 by 81% and then lowering the result by 81% ends at 5.8463, because the second 81% is taken of a bigger number.
