How to work it out

  1. Turn the percentage into a decimal: 100 ÷ 100 = 1
  2. Multiply: 1 × 300 = 300
  3. Check: Work backwards: 300 ÷ 300 × 100 = 100%.

Another method. As a proportion of part to whole: 100/100 = part/300, so part = 100 × 300 ÷ 100 = 300. Both methods always give the same answer.

In a spreadsheet: =100%*300. 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 300.

Mark-ups: pricing an item at 100% of its $300 cost means selling it for $300.

Adding and taking away 100%

Increasing 300 by 100% gives 600. These do not cancel out: raising 300 by 100% and then lowering the result by 100% ends at 0, because the second 100% is taken of a bigger number.

The other way round: 300% of 100. 100% of 300 and 300% of 100 are always equal (both are 100 × 300 ÷ 100 = 300), so you can swap the numbers when one order is easier to work out in your head.
