How to work it out

  1. Turn the percentage into a decimal: 55 ÷ 100 = 0.55
  2. Multiply: 0.55 × 77 = 42.35
  3. Check: Work backwards: 42.35 ÷ 77 × 100 = 55%.

Another method. As a proportion of part to whole: 55/100 = part/77, so part = 55 × 77 ÷ 100 = 42.35. Both methods always give the same answer.

In a spreadsheet: =55%*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

42.35 is the 55% share of 77. The remaining 45% is 34.65, and the two parts add back up to 77.

Discounts: 55% off an item priced $77 saves $42.35, so you pay $34.65.

Adding and taking away 55%

Increasing 77 by 55% gives 119.35 and decreasing it by 55% gives 34.65. These do not cancel out: raising 77 by 55% and then lowering the result by 55% ends at 53.7075, because the second 55% is taken of a bigger number.
