How to work it out

  1. Turn the percentage into a decimal: 20 ÷ 100 = 0.2
  2. Multiply: 0.2 × 86 = 17.2
  3. Check: Work backwards: 17.2 ÷ 86 × 100 = 20%.

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

In a spreadsheet: =20%*86. 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 20% share of 86. The remaining 80% is 68.8, and the two parts add back up to 86.

Discounts: 20% off an item priced $86 saves $17.2, so you pay $68.8.

Adding and taking away 20%

Increasing 86 by 20% gives 103.2 and decreasing it by 20% gives 68.8. These do not cancel out: raising 86 by 20% and then lowering the result by 20% ends at 82.56, because the second 20% is taken of a bigger number.
