How to work it out

  1. Turn the percentage into a decimal: 28 ÷ 100 = 0.28
  2. Multiply: 0.28 × 9 = 2.52
  3. Check: Work backwards: 2.52 ÷ 9 × 100 = 28%.

Another method. As a proportion of part to whole: 28/100 = part/9, so part = 28 × 9 ÷ 100 = 2.52. Both methods always give the same answer.

In a spreadsheet: =28%*9. 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

2.52 is the 28% share of 9. The remaining 72% is 6.48, and the two parts add back up to 9.

Discounts: 28% off an item priced $9 saves $2.52, so you pay $6.48.

Adding and taking away 28%

Increasing 9 by 28% gives 11.52 and decreasing it by 28% gives 6.48. These do not cancel out: raising 9 by 28% and then lowering the result by 28% ends at 8.2944, because the second 28% is taken of a bigger number.
