How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 11 = 7.26
  3. Check: Work backwards: 7.26 ÷ 11 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/11, so part = 66 × 11 ÷ 100 = 7.26. Both methods always give the same answer.

In a spreadsheet: =66%*11. 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

7.26 is the 66% share of 11. The remaining 34% is 3.74, and the two parts add back up to 11.

Discounts: 66% off an item priced $11 saves $7.26, so you pay $3.74.

Adding and taking away 66%

Increasing 11 by 66% gives 18.26 and decreasing it by 66% gives 3.74. These do not cancel out: raising 11 by 66% and then lowering the result by 66% ends at 6.2084, because the second 66% is taken of a bigger number.
