How to work it out

  1. Divide the part by the whole: 51 ÷ 58 = 0.87931
  2. Multiply by 100: 0.87931 × 100 = 87.931%
  3. Check: Work backwards: 87.931% of 58 is 0.87931 × 58 = 51.

Another method. As a proportion of part to whole: 51/58 = p/100, so p = 51 × 100 ÷ 58 = 87.931%. Both methods always give the same answer.

In a spreadsheet: =51/58*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.
