How to work it out

  1. Turn the percentage into a decimal: 10 ÷ 100 = 0.1
  2. Multiply: 0.1 × 11 = 1.1
  3. Check: Work backwards: 1.1 ÷ 11 × 100 = 10%.

Another method. As a proportion of part to whole: 10/100 = part/11, so part = 10 × 11 ÷ 100 = 1.1. Both methods always give the same answer.

In a spreadsheet: =10%*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

1.1 is the 10% share of 11. The remaining 90% is 9.9, and the two parts add back up to 11.

Discounts: 10% off an item priced $11 saves $1.1, so you pay $9.9.

Adding and taking away 10%

Increasing 11 by 10% gives 12.1 and decreasing it by 10% gives 9.9. These do not cancel out: raising 11 by 10% and then lowering the result by 10% ends at 10.89, because the second 10% is taken of a bigger number.
