How to work it out

  1. Turn the percentage into a decimal: 77 ÷ 100 = 0.77
  2. Multiply: 0.77 × 23 = 17.71
  3. Check: Work backwards: 17.71 ÷ 23 × 100 = 77%.

Another method. As a proportion of part to whole: 77/100 = part/23, so part = 77 × 23 ÷ 100 = 17.71. Both methods always give the same answer.

In a spreadsheet: =77%*23. 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

17.71 is the 77% share of 23. The remaining 23% is 5.29, and the two parts add back up to 23.

Discounts: 77% off an item priced $23 saves $17.71, so you pay $5.29.

Adding and taking away 77%

Increasing 23 by 77% gives 40.71 and decreasing it by 77% gives 5.29. These do not cancel out: raising 23 by 77% and then lowering the result by 77% ends at 9.3633, because the second 77% is taken of a bigger number.
