How to work it out

  1. Divide the part by the whole: 31 ÷ 30 = 1.033333
  2. Multiply by 100: 1.033333 × 100 = 103.3333%
  3. Check: Work backwards: 103.3333% of 30 is 1.033333 × 30 = 31.

Another method. As a proportion of part to whole: 31/30 = p/100, so p = 31 × 100 ÷ 30 = 103.3333%. Both methods always give the same answer.

In a spreadsheet: =31/30*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

31 is more than the whole amount (1.033 times as much) of 30. 31 goes past 30 by 1, which is another 3.3333% on top of the whole.

Targets: selling 31 items against a target of 30 means reaching 103.3333% of the target, beating it by 3.3333%.

Turning it around

If you know that 31 is 103.3333% of a number, you can get that number back: 31 ÷ 1.033333 = 30. And 30 as a percentage of 31 is 96.7742%, a different answer, because the whole has changed.
