How to work it out

  1. Divide the part by the whole: 25 ÷ 55 = 0.454545
  2. Multiply by 100: 0.454545 × 100 = 45.4545%
  3. Check: Work backwards: 45.4545% of 55 is 0.454545 × 55 = 25.

Another method. As a proportion of part to whole: 25/55 = p/100, so p = 25 × 100 ÷ 55 = 45.4545%. Both methods always give the same answer.

In a spreadsheet: =25/55*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.
