How to work it out

  1. Turn the percentage into a decimal: 85 ÷ 100 = 0.85
  2. Multiply: 0.85 × 66 = 56.1
  3. Check: Work backwards: 56.1 ÷ 66 × 100 = 85%.

Another method. As a proportion of part to whole: 85/100 = part/66, so part = 85 × 66 ÷ 100 = 56.1. Both methods always give the same answer.

In a spreadsheet: =85%*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

56.1 is the 85% share of 66. The remaining 15% is 9.9, and the two parts add back up to 66.

Discounts: 85% off an item priced $66 saves $56.1, so you pay $9.9.

Adding and taking away 85%

Increasing 66 by 85% gives 122.1 and decreasing it by 85% gives 9.9. These do not cancel out: raising 66 by 85% and then lowering the result by 85% ends at 18.315, because the second 85% is taken of a bigger number.
