How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 90 = 24.3
  3. Check: Work backwards: 24.3 ÷ 90 × 100 = 27%.

Another method. As a proportion of part to whole: 27/100 = part/90, so part = 27 × 90 ÷ 100 = 24.3. Both methods always give the same answer.

In a spreadsheet: =27%*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

24.3 is the 27% share of 90. The remaining 73% is 65.7, and the two parts add back up to 90.

Discounts: 27% off an item priced $90 saves $24.3, so you pay $65.7.

Adding and taking away 27%

Increasing 90 by 27% gives 114.3 and decreasing it by 27% gives 65.7. These do not cancel out: raising 90 by 27% and then lowering the result by 27% ends at 83.439, because the second 27% is taken of a bigger number.
