How to work it out

  1. Turn the percentage into a decimal: 88 ÷ 100 = 0.88
  2. Multiply: 0.88 × 78 = 68.64
  3. Check: Work backwards: 68.64 ÷ 78 × 100 = 88%.

Another method. As a proportion of part to whole: 88/100 = part/78, so part = 88 × 78 ÷ 100 = 68.64. Both methods always give the same answer.

In a spreadsheet: =88%*78. 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

68.64 is the 88% share of 78. The remaining 12% is 9.36, and the two parts add back up to 78.

Discounts: 88% off an item priced $78 saves $68.64, so you pay $9.36.

Adding and taking away 88%

Increasing 78 by 88% gives 146.64 and decreasing it by 88% gives 9.36. These do not cancel out: raising 78 by 88% and then lowering the result by 88% ends at 17.5968, because the second 88% is taken of a bigger number.
