How to work it out
- Turn the percentage into a decimal: 13 ÷ 100 = 0.13
- Multiply: 0.13 × 90 = 11.7
- Check: Work backwards: 11.7 ÷ 90 × 100 = 13%.
Another method. As a proportion of part to whole: 13/100 = part/90, so part = 13 × 90 ÷ 100 = 11.7. Both methods always give the same answer.
In a spreadsheet: =13%*90. 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
11.7 is the 13% share of 90. The remaining 87% is 78.3, and the two parts add back up to 90.
Discounts: 13% off an item priced $90 saves $11.7, so you pay $78.3.
Adding and taking away 13%
Increasing 90 by 13% gives 101.7 and decreasing it by 13% gives 78.3. These do not cancel out: raising 90 by 13% and then lowering the result by 13% ends at 88.479, because the second 13% is taken of a bigger number.
