How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 66 = 43.56
  3. Check: Work backwards: 43.56 ÷ 66 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/66, so part = 66 × 66 ÷ 100 = 43.56. Both methods always give the same answer.

In a spreadsheet: =66%*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

43.56 is the 66% share of 66. The remaining 34% is 22.44, and the two parts add back up to 66.

Discounts: 66% off an item priced $66 saves $43.56, so you pay $22.44.

Adding and taking away 66%

Increasing 66 by 66% gives 109.56 and decreasing it by 66% gives 22.44. These do not cancel out: raising 66 by 66% and then lowering the result by 66% ends at 37.2504, because the second 66% is taken of a bigger number.
