How to work it out

  1. Divide the part by the whole: 58 ÷ 40 = 1.45
  2. Multiply by 100: 1.45 × 100 = 145%
  3. Check: Work backwards: 145% of 40 is 1.45 × 40 = 58.

Another method. As a proportion of part to whole: 58/40 = p/100, so p = 58 × 100 ÷ 40 = 145%. Both methods always give the same answer.

In a spreadsheet: =58/40*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

58 is more than the whole amount (1.45 times as much) of 40. 58 goes past 40 by 18, which is another 45% on top of the whole.

Targets: selling 58 items against a target of 40 means reaching 145% of the target, beating it by 45%.

Turning it around

If you know that 58 is 145% of a number, you can get that number back: 58 ÷ 1.45 = 40. And 40 as a percentage of 58 is 68.9655%, a different answer, because the whole has changed.
