How to work it out
- Turn the percentage into a decimal: 20 ÷ 100 = 0.2
- Multiply: 0.2 × 85 = 17
- Check: Work backwards: 17 ÷ 85 × 100 = 20%.
Another method. As a proportion of part to whole: 20/100 = part/85, so part = 20 × 85 ÷ 100 = 17. Both methods always give the same answer.
In a spreadsheet: =20%*85. 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
17 is the 20% share of 85. The remaining 80% is 68, and the two parts add back up to 85.
Discounts: 20% off an item priced $85 saves $17, so you pay $68.
Adding and taking away 20%
Increasing 85 by 20% gives 102 and decreasing it by 20% gives 68. These do not cancel out: raising 85 by 20% and then lowering the result by 20% ends at 81.6, because the second 20% is taken of a bigger number.
