How to work it out
- Turn the percentage into a decimal: 31 ÷ 100 = 0.31
- Multiply: 0.31 × 20 = 6.2
- Check: Work backwards: 6.2 ÷ 20 × 100 = 31%.
Another method. As a proportion of part to whole: 31/100 = part/20, so part = 31 × 20 ÷ 100 = 6.2. Both methods always give the same answer.
In a spreadsheet: =31%*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
6.2 is the 31% share of 20. The remaining 69% is 13.8, and the two parts add back up to 20.
Discounts: 31% off an item priced $20 saves $6.2, so you pay $13.8.
Adding and taking away 31%
Increasing 20 by 31% gives 26.2 and decreasing it by 31% gives 13.8. These do not cancel out: raising 20 by 31% and then lowering the result by 31% ends at 18.078, because the second 31% is taken of a bigger number.
