How to work it out

  1. Divide the part by the whole: 99 ÷ 40 = 2.475
  2. Multiply by 100: 2.475 × 100 = 247.5%
  3. Check: Work backwards: 247.5% of 40 is 2.475 × 40 = 99.

Another method. As a proportion of part to whole: 99/40 = p/100, so p = 99 × 100 ÷ 40 = 247.5%. Both methods always give the same answer.

In a spreadsheet: =99/40*100. Dividing the wrong way round (whole ÷ part) gives a different answer. The number after “of” is always the whole, so it goes on the bottom.

What the result means

99 is more than the whole amount (2.475 times as much) of 40. 99 goes past 40 by 59, which is another 147.5% on top of the whole.

Targets: selling 99 items against a target of 40 means reaching 247.5% of the target, beating it by 147.5%.

Turning it around

If you know that 99 is 247.5% of a number, you can get that number back: 99 ÷ 2.475 = 40. And 40 as a percentage of 99 is 40.404%, a different answer, because the whole has changed.
