How to work it out

  1. Turn the percentage into a decimal: 1 ÷ 100 = 0.01
  2. Multiply: 0.01 × 27 = 0.27
  3. Check: Work backwards: 0.27 ÷ 27 × 100 = 1%.

Another method. As a proportion of part to whole: 1/100 = part/27, so part = 1 × 27 ÷ 100 = 0.27. Both methods always give the same answer.

In a spreadsheet: =1%*27. 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

0.27 is the 1% share of 27. The remaining 99% is 26.73, and the two parts add back up to 27.

Discounts: 1% off an item priced $27 saves $0.27, so you pay $26.73.

Adding and taking away 1%

Increasing 27 by 1% gives 27.27 and decreasing it by 1% gives 26.73. These do not cancel out: raising 27 by 1% and then lowering the result by 1% ends at 26.9973, because the second 1% is taken of a bigger number.
