How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 77 = 20.79
  3. Check: Work backwards: 20.79 ÷ 77 × 100 = 27%.

Another method. As a proportion of part to whole: 27/100 = part/77, so part = 27 × 77 ÷ 100 = 20.79. Both methods always give the same answer.

In a spreadsheet: =27%*77. 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

20.79 is the 27% share of 77. The remaining 73% is 56.21, and the two parts add back up to 77.

Discounts: 27% off an item priced $77 saves $20.79, so you pay $56.21.

Adding and taking away 27%

Increasing 77 by 27% gives 97.79 and decreasing it by 27% gives 56.21. These do not cancel out: raising 77 by 27% and then lowering the result by 27% ends at 71.3867, because the second 27% is taken of a bigger number.
