How to work it out

  1. Divide the part by the whole: 31 ÷ 21 = 1.47619
  2. Multiply by 100: 1.47619 × 100 = 147.619%
  3. Check: Work backwards: 147.619% of 21 is 1.47619 × 21 = 31.

Another method. As a proportion of part to whole: 31/21 = p/100, so p = 31 × 100 ÷ 21 = 147.619%. Both methods always give the same answer.

In a spreadsheet: =31/21*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 (1.476 times as much) of 21. 31 goes past 21 by 10, which is another 47.619% on top of the whole.

Targets: selling 31 items against a target of 21 means reaching 147.619% of the target, beating it by 47.619%.
