How to work it out

  1. Turn the percentage into a decimal: 66 ÷ 100 = 0.66
  2. Multiply: 0.66 × 28 = 18.48
  3. Check: Work backwards: 18.48 ÷ 28 × 100 = 66%.

Another method. As a proportion of part to whole: 66/100 = part/28, so part = 66 × 28 ÷ 100 = 18.48. Both methods always give the same answer.

In a spreadsheet: =66%*28. 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

18.48 is the 66% share of 28. The remaining 34% is 9.52, and the two parts add back up to 28.

Discounts: 66% off an item priced $28 saves $18.48, so you pay $9.52.

Adding and taking away 66%

Increasing 28 by 66% gives 46.48 and decreasing it by 66% gives 9.52. These do not cancel out: raising 28 by 66% and then lowering the result by 66% ends at 15.8032, because the second 66% is taken of a bigger number.
