How to work it out

  1. Turn the percentage into a decimal: 12 ÷ 100 = 0.12
  2. Multiply: 0.12 × 90 = 10.8
  3. Check: Work backwards: 10.8 ÷ 90 × 100 = 12%.

Another method. As a proportion of part to whole: 12/100 = part/90, so part = 12 × 90 ÷ 100 = 10.8. Both methods always give the same answer.

In a spreadsheet: =12%*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

10.8 is the 12% share of 90. The remaining 88% is 79.2, and the two parts add back up to 90.

Discounts: 12% off an item priced $90 saves $10.8, so you pay $79.2.

Adding and taking away 12%

Increasing 90 by 12% gives 100.8 and decreasing it by 12% gives 79.2. These do not cancel out: raising 90 by 12% and then lowering the result by 12% ends at 88.704, because the second 12% is taken of a bigger number.
