How to work it out

  1. Turn the percentage into a decimal: 91 ÷ 100 = 0.91
  2. Multiply: 0.91 × 66 = 60.06
  3. Check: Work backwards: 60.06 ÷ 66 × 100 = 91%.

Another method. As a proportion of part to whole: 91/100 = part/66, so part = 91 × 66 ÷ 100 = 60.06. Both methods always give the same answer.

In a spreadsheet: =91%*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

60.06 is the 91% share of 66. The remaining 9% is 5.94, and the two parts add back up to 66.

Discounts: 91% off an item priced $66 saves $60.06, so you pay $5.94.

Adding and taking away 91%

Increasing 66 by 91% gives 126.06 and decreasing it by 91% gives 5.94. These do not cancel out: raising 66 by 91% and then lowering the result by 91% ends at 11.3454, because the second 91% is taken of a bigger number.
