How to work it out

  1. Divide the part by the whole: 25 ÷ 90 = 0.277778
  2. Multiply by 100: 0.277778 × 100 = 27.7778%
  3. Check: Work backwards: 27.7778% of 90 is 0.277778 × 90 = 25.

Another method. As a proportion of part to whole: 25/90 = p/100, so p = 25 × 100 ÷ 90 = 27.7778%. Both methods always give the same answer.

In a spreadsheet: =25/90*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.

What the result means
