How to work it out

  1. Divide the part by the whole: 40 ÷ 28 = 1.428571
  2. Multiply by 100: 1.428571 × 100 = 142.8571%
  3. Check: Work backwards: 142.8571% of 28 is 1.428571 × 28 = 40.

Another method. As a proportion of part to whole: 40/28 = p/100, so p = 40 × 100 ÷ 28 = 142.8571%. Both methods always give the same answer.

In a spreadsheet: =40/28*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
