How to work it out

  1. Divide the part by the whole: 105 ÷ 250 = 0.42
  2. Multiply by 100: 0.42 × 100 = 42%
  3. Check: Work backwards: 42% of 250 is 0.42 × 250 = 105.

Another method. As a proportion of part to whole: 105/250 = p/100, so p = 105 × 100 ÷ 250 = 42%. Both methods always give the same answer.

In a spreadsheet: =105/250*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.
