How to work it out

  1. Turn the percentage into a decimal: 78 ÷ 100 = 0.78
  2. Multiply: 0.78 × 11 = 8.58
  3. Check: Work backwards: 8.58 ÷ 11 × 100 = 78%.

Another method. As a proportion of part to whole: 78/100 = part/11, so part = 78 × 11 ÷ 100 = 8.58. Both methods always give the same answer.

In a spreadsheet: =78%*11. 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

8.58 is the 78% share of 11. The remaining 22% is 2.42, and the two parts add back up to 11.

Discounts: 78% off an item priced $11 saves $8.58, so you pay $2.42.

Adding and taking away 78%

Increasing 11 by 78% gives 19.58 and decreasing it by 78% gives 2.42. These do not cancel out: raising 11 by 78% and then lowering the result by 78% ends at 4.3076, because the second 78% is taken of a bigger number.
