How to work it out

  1. Turn the percentage into a decimal: 77 ÷ 100 = 0.77
  2. Multiply: 0.77 × 66 = 50.82
  3. Check: Work backwards: 50.82 ÷ 66 × 100 = 77%.

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

In a spreadsheet: =77%*66. 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 77% share of 66. The remaining 23% is 15.18, and the two parts add back up to 66.

Discounts: 77% off an item priced $66 saves $50.82, so you pay $15.18.

Adding and taking away 77%

Increasing 66 by 77% gives 116.82 and decreasing it by 77% gives 15.18. These do not cancel out: raising 66 by 77% and then lowering the result by 77% ends at 26.8686, because the second 77% is taken of a bigger number.
