How to work it out

  1. Turn the percentage into a decimal: 280 ÷ 100 = 2.8
  2. Multiply: 2.8 × 25 = 70
  3. Check: Work backwards: 70 ÷ 25 × 100 = 280%.

Another method. As a proportion of part to whole: 280/100 = part/25, so part = 280 × 25 ÷ 100 = 70. Both methods always give the same answer.

In a spreadsheet: =280%*25. 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 280% is more than 100%, the answer is bigger than 25: it is 2.8 times 25.

Mark-ups: pricing an item at 280% of its $25 cost means selling it for $70.

Adding and taking away 280%

Increasing 25 by 280% gives 95. These do not cancel out: raising 25 by 280% and then lowering the result by 280% ends at -171, because the second 280% is taken of a bigger number.
