How to work it out

  1. Turn the percentage into a decimal: 5 ÷ 100 = 0.05
  2. Multiply: 0.05 × 20 = 1
  3. Check: Work backwards: 1 ÷ 20 × 100 = 5%.

Another method. As a proportion of part to whole: 5/100 = part/20, so part = 5 × 20 ÷ 100 = 1. Both methods always give the same answer.

In a spreadsheet: =5%*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

1 is the 5% share of 20. The remaining 95% is 19, and the two parts add back up to 20.

Discounts: 5% off an item priced $20 saves $1, so you pay $19.

Adding and taking away 5%

Increasing 20 by 5% gives 21 and decreasing it by 5% gives 19. These do not cancel out: raising 20 by 5% and then lowering the result by 5% ends at 19.95, because the second 5% is taken of a bigger number.
