How to work it out
- Turn the percentage into a decimal: 24 ÷ 100 = 0.24
- Multiply: 0.24 × 90 = 21.6
- Check: Work backwards: 21.6 ÷ 90 × 100 = 24%.
Another method. As a proportion of part to whole: 24/100 = part/90, so part = 24 × 90 ÷ 100 = 21.6. Both methods always give the same answer.
In a spreadsheet: =24%*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
21.6 is the 24% share of 90. The remaining 76% is 68.4, and the two parts add back up to 90.
Discounts: 24% off an item priced $90 saves $21.6, so you pay $68.4.
Adding and taking away 24%
Increasing 90 by 24% gives 111.6 and decreasing it by 24% gives 68.4. These do not cancel out: raising 90 by 24% and then lowering the result by 24% ends at 84.816, because the second 24% is taken of a bigger number.
