How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 85 = 66.3
  3. Check: Work backwards: 66.3 ÷ 85 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/85, so part = 78 × 85 ÷ 100 = 66.3. Both methods always give the same answer.

In a spreadsheet: =78%*85. 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

66.3 is the 78% share of 85. The remaining 22% is 18.7, and the two parts add back up to 85.

Discounts: 78% off an item priced $85 saves $66.3, so you pay $18.7.

Adding and taking away 78%

Increasing 85 by 78% gives 151.3 and decreasing it by 78% gives 18.7. These do not cancel out: raising 85 by 78% and then lowering the result by 78% ends at 33.286, because the second 78% is taken of a bigger number.
