How to work it out

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

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

In a spreadsheet: =100%*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

100% of a number is the number itself, so the answer is 27.

Mark-ups: pricing an item at 100% of its $27 cost means selling it for $27.

Adding and taking away 100%

Increasing 27 by 100% gives 54. These do not cancel out: raising 27 by 100% and then lowering the result by 100% ends at 0, because the second 100% is taken of a bigger number.
