How to work it out

  1. Turn the percentage into a decimal: 55 ÷ 100 = 0.55
  2. Multiply: 0.55 × 66 = 36.3
  3. Check: Work backwards: 36.3 ÷ 66 × 100 = 55%.

Another method. As a proportion of part to whole: 55/100 = part/66, so part = 55 × 66 ÷ 100 = 36.3. Both methods always give the same answer.

In a spreadsheet: =55%*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

36.3 is the 55% share of 66. The remaining 45% is 29.7, and the two parts add back up to 66.

Discounts: 55% off an item priced $66 saves $36.3, so you pay $29.7.

Adding and taking away 55%

Increasing 66 by 55% gives 102.3 and decreasing it by 55% gives 29.7. These do not cancel out: raising 66 by 55% and then lowering the result by 55% ends at 46.035, because the second 55% is taken of a bigger number.
