How to work it out

  1. Turn the percentage into a decimal: 72 ÷ 100 = 0.72
  2. Multiply: 0.72 × 77 = 55.44
  3. Check: Work backwards: 55.44 ÷ 77 × 100 = 72%.

Another method. As a proportion of part to whole: 72/100 = part/77, so part = 72 × 77 ÷ 100 = 55.44. Both methods always give the same answer.

In a spreadsheet: =72%*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

55.44 is the 72% share of 77. The remaining 28% is 21.56, and the two parts add back up to 77.

Discounts: 72% off an item priced $77 saves $55.44, so you pay $21.56.

Adding and taking away 72%

Increasing 77 by 72% gives 132.44 and decreasing it by 72% gives 21.56. These do not cancel out: raising 77 by 72% and then lowering the result by 72% ends at 37.0832, because the second 72% is taken of a bigger number.
