How to work it out

  1. Divide the part by the whole: 55 ÷ 87 = 0.632184
  2. Multiply by 100: 0.632184 × 100 = 63.2184%
  3. Check: Work backwards: 63.2184% of 87 is 0.632184 × 87 = 55.

Another method. As a proportion of part to whole: 55/87 = p/100, so p = 55 × 100 ÷ 87 = 63.2184%. Both methods always give the same answer.

In a spreadsheet: =55/87*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.
