How to work it out

  1. Turn the percentage into a decimal: 27 ÷ 100 = 0.27
  2. Multiply: 0.27 × 66 = 17.82
  3. Check: Work backwards: 17.82 ÷ 66 × 100 = 27%.

Another method. As a proportion of part to whole: 27/100 = part/66, so part = 27 × 66 ÷ 100 = 17.82. Both methods always give the same answer.

In a spreadsheet: =27%*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

17.82 is the 27% share of 66. The remaining 73% is 48.18, and the two parts add back up to 66.

Discounts: 27% off an item priced $66 saves $17.82, so you pay $48.18.

Adding and taking away 27%

Increasing 66 by 27% gives 83.82 and decreasing it by 27% gives 48.18. These do not cancel out: raising 66 by 27% and then lowering the result by 27% ends at 61.1886, because the second 27% is taken of a bigger number.
