How to work it out

  1. Turn the percentage into a decimal: 450 ÷ 100 = 4.5
  2. Multiply: 4.5 × 10 = 45
  3. Check: Work backwards: 45 ÷ 10 × 100 = 450%.

Another method. As a proportion of part to whole: 450/100 = part/10, so part = 450 × 10 ÷ 100 = 45. Both methods always give the same answer.

In a spreadsheet: =450%*10. 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 450% is more than 100%, the answer is bigger than 10: it is 4.5 times 10.

Mark-ups: pricing an item at 450% of its $10 cost means selling it for $45.

Adding and taking away 450%

Increasing 10 by 450% gives 55. These do not cancel out: raising 10 by 450% and then lowering the result by 450% ends at -192.5, because the second 450% is taken of a bigger number.
