How to work it out

  1. Turn the percentage into a decimal: 80 ÷ 100 = 0.8
  2. Multiply: 0.8 × 11 = 8.8
  3. Check: Work backwards: 8.8 ÷ 11 × 100 = 80%.

Another method. As a proportion of part to whole: 80/100 = part/11, so part = 80 × 11 ÷ 100 = 8.8. Both methods always give the same answer.

In a spreadsheet: =80%*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

8.8 is the 80% share of 11. The remaining 20% is 2.2, and the two parts add back up to 11.

Discounts: 80% off an item priced $11 saves $8.8, so you pay $2.2.

Adding and taking away 80%

Increasing 11 by 80% gives 19.8 and decreasing it by 80% gives 2.2. These do not cancel out: raising 11 by 80% and then lowering the result by 80% ends at 3.96, because the second 80% is taken of a bigger number.
