How to work it out

  1. Turn the percentage into a decimal: 11 ÷ 100 = 0.11
  2. Multiply: 0.11 × 1 = 0.11
  3. Check: Work backwards: 0.11 ÷ 1 × 100 = 11%.

Another method. As a proportion of part to whole: 11/100 = part/1, so part = 11 × 1 ÷ 100 = 0.11. Both methods always give the same answer.

In a spreadsheet: =11%*1. 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

0.11 is the 11% share of 1. The remaining 89% is 0.89, and the two parts add back up to 1.

Discounts: 11% off an item priced $1 saves $0.11, so you pay $0.89.

Adding and taking away 11%

Increasing 1 by 11% gives 1.11 and decreasing it by 11% gives 0.89. These do not cancel out: raising 1 by 11% and then lowering the result by 11% ends at 0.9879, because the second 11% is taken of a bigger number.
