How to work it out

  1. Turn the percentage into a decimal: 20 ÷ 100 = 0.2
  2. Multiply: 0.2 × 5 = 1
  3. Check: Work backwards: 1 ÷ 5 × 100 = 20%.

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

In a spreadsheet: =20%*5. 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 20% share of 5. The remaining 80% is 4, and the two parts add back up to 5.

Discounts: 20% off an item priced $5 saves $1, so you pay $4.

Adding and taking away 20%

Increasing 5 by 20% gives 6 and decreasing it by 20% gives 4. These do not cancel out: raising 5 by 20% and then lowering the result by 20% ends at 4.8, because the second 20% is taken of a bigger number.
