How to work it out

  1. Turn the percentage into a decimal: 86 ÷ 100 = 0.86
  2. Multiply: 0.86 × 20 = 17.2
  3. Check: Work backwards: 17.2 ÷ 20 × 100 = 86%.

Another method. As a proportion of part to whole: 86/100 = part/20, so part = 86 × 20 ÷ 100 = 17.2. Both methods always give the same answer.

In a spreadsheet: =86%*20. 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

17.2 is the 86% share of 20. The remaining 14% is 2.8, and the two parts add back up to 20.

Discounts: 86% off an item priced $20 saves $17.2, so you pay $2.8.

Adding and taking away 86%

Increasing 20 by 86% gives 37.2 and decreasing it by 86% gives 2.8. These do not cancel out: raising 20 by 86% and then lowering the result by 86% ends at 5.208, because the second 86% is taken of a bigger number.
