How to work it out

  1. Divide the part by the whole: 91 ÷ 20 = 4.55
  2. Multiply by 100: 4.55 × 100 = 455%
  3. Check: Work backwards: 455% of 20 is 4.55 × 20 = 91.

Another method. As a proportion of part to whole: 91/20 = p/100, so p = 91 × 100 ÷ 20 = 455%. Both methods always give the same answer.

In a spreadsheet: =91/20*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

91 is more than the whole amount (4.55 times as much) of 20. 91 goes past 20 by 71, which is another 355% on top of the whole.

Targets: selling 91 items against a target of 20 means reaching 455% of the target, beating it by 355%.

Turning it around

If you know that 91 is 455% of a number, you can get that number back: 91 ÷ 4.55 = 20. And 20 as a percentage of 91 is 21.978%, a different answer, because the whole has changed.
