How to work it out

  1. Divide the part by the whole: 30 ÷ 28 = 1.071429
  2. Multiply by 100: 1.071429 × 100 = 107.1429%
  3. Check: Work backwards: 107.1429% of 28 is 1.071429 × 28 = 30.

Another method. As a proportion of part to whole: 30/28 = p/100, so p = 30 × 100 ÷ 28 = 107.1429%. Both methods always give the same answer.

In a spreadsheet: =30/28*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
