How to work it out
- Turn the percentage into a decimal: 30 ÷ 100 = 0.3
- Multiply: 0.3 × 20 = 6
- Check: Work backwards: 6 ÷ 20 × 100 = 30%.
Another method. As a proportion of part to whole: 30/100 = part/20, so part = 30 × 20 ÷ 100 = 6. Both methods always give the same answer.
In a spreadsheet: =30%*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 is the 30% share of 20. The remaining 70% is 14, and the two parts add back up to 20.
Discounts: 30% off an item priced $20 saves $6, so you pay $14.
Adding and taking away 30%
Increasing 20 by 30% gives 26 and decreasing it by 30% gives 14. These do not cancel out: raising 20 by 30% and then lowering the result by 30% ends at 18.2, because the second 30% is taken of a bigger number.
