How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 27 = 17.82
  3. Check: Work backwards: 17.82 ÷ 27 × 100 = 66%.

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

In a spreadsheet: =66%*27. 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 66% share of 27. The remaining 34% is 9.18, and the two parts add back up to 27.

Discounts: 66% off an item priced $27 saves $17.82, so you pay $9.18.

Adding and taking away 66%

Increasing 27 by 66% gives 44.82 and decreasing it by 66% gives 9.18. These do not cancel out: raising 27 by 66% and then lowering the result by 66% ends at 15.2388, because the second 66% is taken of a bigger number.
