How to work it out

  1. Turn the percentage into a decimal: 81 ÷ 100 = 0.81
  2. Multiply: 0.81 × 36 = 29.16
  3. Check: Work backwards: 29.16 ÷ 36 × 100 = 81%.

Another method. As a proportion of part to whole: 81/100 = part/36, so part = 81 × 36 ÷ 100 = 29.16. Both methods always give the same answer.

In a spreadsheet: =81%*36. 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

29.16 is the 81% share of 36. The remaining 19% is 6.84, and the two parts add back up to 36.

Discounts: 81% off an item priced $36 saves $29.16, so you pay $6.84.

Adding and taking away 81%

Increasing 36 by 81% gives 65.16 and decreasing it by 81% gives 6.84. These do not cancel out: raising 36 by 81% and then lowering the result by 81% ends at 12.3804, because the second 81% is taken of a bigger number.
