How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 77 = 50.82
  3. Check: Work backwards: 50.82 ÷ 77 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/77, so part = 66 × 77 ÷ 100 = 50.82. Both methods always give the same answer.

In a spreadsheet: =66%*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

50.82 is the 66% share of 77. The remaining 34% is 26.18, and the two parts add back up to 77.

Discounts: 66% off an item priced $77 saves $50.82, so you pay $26.18.

Adding and taking away 66%

Increasing 77 by 66% gives 127.82 and decreasing it by 66% gives 26.18. These do not cancel out: raising 77 by 66% and then lowering the result by 66% ends at 43.4588, because the second 66% is taken of a bigger number.
