How to work it out

  1. Divide the part by the whole: 51 ÷ 18 = 2.833333
  2. Multiply by 100: 2.833333 × 100 = 283.3333%
  3. Check: Work backwards: 283.3333% of 18 is 2.833333 × 18 = 51.

Another method. As a proportion of part to whole: 51/18 = p/100, so p = 51 × 100 ÷ 18 = 283.3333%. Both methods always give the same answer.

In a spreadsheet: =51/18*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

Targets: selling 51 items against a target of 18 means reaching 283.3333% of the target, beating it by 183.3333%.

Turning it around
