How to work it out

  1. Turn the percentage into a decimal: 17 ÷ 100 = 0.17
  2. Multiply: 0.17 × 20 = 3.4
  3. Check: Work backwards: 3.4 ÷ 20 × 100 = 17%.

Another method. As a proportion of part to whole: 17/100 = part/20, so part = 17 × 20 ÷ 100 = 3.4. Both methods always give the same answer.

In a spreadsheet: =17%*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

3.4 is the 17% share of 20. The remaining 83% is 16.6, and the two parts add back up to 20.

Discounts: 17% off an item priced $20 saves $3.4, so you pay $16.6.

Adding and taking away 17%

Increasing 20 by 17% gives 23.4 and decreasing it by 17% gives 16.6. These do not cancel out: raising 20 by 17% and then lowering the result by 17% ends at 19.422, because the second 17% is taken of a bigger number.
