How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 87 = 67.86
  3. Check: Work backwards: 67.86 ÷ 87 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/87, so part = 78 × 87 ÷ 100 = 67.86. Both methods always give the same answer.

In a spreadsheet: =78%*87. 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

67.86 is the 78% share of 87. The remaining 22% is 19.14, and the two parts add back up to 87.

Discounts: 78% off an item priced $87 saves $67.86, so you pay $19.14.

Adding and taking away 78%

Increasing 87 by 78% gives 154.86 and decreasing it by 78% gives 19.14. These do not cancel out: raising 87 by 78% and then lowering the result by 78% ends at 34.0692, because the second 78% is taken of a bigger number.
