How to work it out

  1. Turn the percentage into a decimal: 250 ÷ 100 = 2.5
  2. Multiply: 2.5 × 40 = 100
  3. Check: Work backwards: 100 ÷ 40 × 100 = 250%.

Another method. As a proportion of part to whole: 250/100 = part/40, so part = 250 × 40 ÷ 100 = 100. Both methods always give the same answer.

In a spreadsheet: =250%*40. 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

Because 250% is more than 100%, the answer is bigger than 40: it is 2.5 times 40.

Mark-ups: pricing an item at 250% of its $40 cost means selling it for $100.

Adding and taking away 250%

Increasing 40 by 250% gives 140. These do not cancel out: raising 40 by 250% and then lowering the result by 250% ends at -210, because the second 250% is taken of a bigger number.
