How to work it out

  1. Divide the part by the whole: 57 ÷ 89 = 0.640449
  2. Multiply by 100: 0.640449 × 100 = 64.0449%
  3. Check: Work backwards: 64.0449% of 89 is 0.640449 × 89 = 57.

Another method. As a proportion of part to whole: 57/89 = p/100, so p = 57 × 100 ÷ 89 = 64.0449%. Both methods always give the same answer.

In a spreadsheet: =57/89*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.
