How to work it out
- Turn the percentage into a decimal: 20 ÷ 100 = 0.2
- Multiply: 0.2 × 20 = 4
- Check: Work backwards: 4 ÷ 20 × 100 = 20%.
Another method. As a proportion of part to whole: 20/100 = part/20, so part = 20 × 20 ÷ 100 = 4. Both methods always give the same answer.
In a spreadsheet: =20%*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
4 is the 20% share of 20. The remaining 80% is 16, and the two parts add back up to 20.
Discounts: 20% off an item priced $20 saves $4, so you pay $16.
Adding and taking away 20%
Increasing 20 by 20% gives 24 and decreasing it by 20% gives 16. These do not cancel out: raising 20 by 20% and then lowering the result by 20% ends at 19.2, because the second 20% is taken of a bigger number.
