How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 55 = 36.3
  3. Check: Work backwards: 36.3 ÷ 55 × 100 = 66%.

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

In a spreadsheet: =66%*55. 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 66% share of 55. The remaining 34% is 18.7, and the two parts add back up to 55.

Discounts: 66% off an item priced $55 saves $36.3, so you pay $18.7.

Adding and taking away 66%

Increasing 55 by 66% gives 91.3 and decreasing it by 66% gives 18.7. These do not cancel out: raising 55 by 66% and then lowering the result by 66% ends at 31.042, because the second 66% is taken of a bigger number.
