How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 23 = 15.18
  3. Check: Work backwards: 15.18 ÷ 23 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/23, so part = 66 × 23 ÷ 100 = 15.18. Both methods always give the same answer.

In a spreadsheet: =66%*23. 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

15.18 is the 66% share of 23. The remaining 34% is 7.82, and the two parts add back up to 23.

Discounts: 66% off an item priced $23 saves $15.18, so you pay $7.82.

Adding and taking away 66%

Increasing 23 by 66% gives 38.18 and decreasing it by 66% gives 7.82. These do not cancel out: raising 23 by 66% and then lowering the result by 66% ends at 12.9812, because the second 66% is taken of a bigger number.
