How to work it out

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

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

In a spreadsheet: =77%*100. 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

77 is the 77% share of 100. The remaining 23% is 23, and the two parts add back up to 100.

Discounts: 77% off an item priced $100 saves $77, so you pay $23.

Adding and taking away 77%

Increasing 100 by 77% gives 177 and decreasing it by 77% gives 23. These do not cancel out: raising 100 by 77% and then lowering the result by 77% ends at 40.71, because the second 77% is taken of a bigger number.
