How to work it out
- Turn the percentage into a decimal: 40 ÷ 100 = 0.4
- Multiply: 0.4 × 17 = 6.8
- Check: Work backwards: 6.8 ÷ 17 × 100 = 40%.
Another method. As a proportion of part to whole: 40/100 = part/17, so part = 40 × 17 ÷ 100 = 6.8. Both methods always give the same answer.
In a spreadsheet: =40%*17. 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
6.8 is the 40% share of 17. The remaining 60% is 10.2, and the two parts add back up to 17.
Discounts: 40% off an item priced $17 saves $6.8, so you pay $10.2.
Adding and taking away 40%
Increasing 17 by 40% gives 23.8 and decreasing it by 40% gives 10.2. These do not cancel out: raising 17 by 40% and then lowering the result by 40% ends at 14.28, because the second 40% is taken of a bigger number.
