How to work it out
- Turn the percentage into a decimal: 77 ÷ 100 = 0.77
- Multiply: 0.77 × 20 = 15.4
- Check: Work backwards: 15.4 ÷ 20 × 100 = 77%.
Another method. As a proportion of part to whole: 77/100 = part/20, so part = 77 × 20 ÷ 100 = 15.4. Both methods always give the same answer.
In a spreadsheet: =77%*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
15.4 is the 77% share of 20. The remaining 23% is 4.6, and the two parts add back up to 20.
Discounts: 77% off an item priced $20 saves $15.4, so you pay $4.6.
Adding and taking away 77%
Increasing 20 by 77% gives 35.4 and decreasing it by 77% gives 4.6. These do not cancel out: raising 20 by 77% and then lowering the result by 77% ends at 8.142, because the second 77% is taken of a bigger number.
