How to work it out

  1. Turn the percentage into a decimal: 77 ÷ 100 = 0.77
  2. Multiply: 0.77 × 28 = 21.56
  3. Check: Work backwards: 21.56 ÷ 28 × 100 = 77%.

Another method. As a proportion of part to whole: 77/100 = part/28, so part = 77 × 28 ÷ 100 = 21.56. Both methods always give the same answer.

In a spreadsheet: =77%*28. 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

21.56 is the 77% share of 28. The remaining 23% is 6.44, and the two parts add back up to 28.

Discounts: 77% off an item priced $28 saves $21.56, so you pay $6.44.

Adding and taking away 77%

Increasing 28 by 77% gives 49.56 and decreasing it by 77% gives 6.44. These do not cancel out: raising 28 by 77% and then lowering the result by 77% ends at 11.3988, because the second 77% is taken of a bigger number.
