How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 33 = 21.78
  3. Check: Work backwards: 21.78 ÷ 33 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/33, so part = 66 × 33 ÷ 100 = 21.78. Both methods always give the same answer.

In a spreadsheet: =66%*33. 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

21.78 is the 66% share of 33. The remaining 34% is 11.22, and the two parts add back up to 33.

Discounts: 66% off an item priced $33 saves $21.78, so you pay $11.22.

Adding and taking away 66%

Increasing 33 by 66% gives 54.78 and decreasing it by 66% gives 11.22. These do not cancel out: raising 33 by 66% and then lowering the result by 66% ends at 18.6252, because the second 66% is taken of a bigger number.
