How to work it out

  1. Divide the part by the whole: 57 ÷ 42 = 1.357143
  2. Multiply by 100: 1.357143 × 100 = 135.7143%
  3. Check: Work backwards: 135.7143% of 42 is 1.357143 × 42 = 57.

Another method. As a proportion of part to whole: 57/42 = p/100, so p = 57 × 100 ÷ 42 = 135.7143%. Both methods always give the same answer.

In a spreadsheet: =57/42*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.
