How to work it out

  1. Divide the part by the whole: 83 ÷ 21 = 3.952381
  2. Multiply by 100: 3.952381 × 100 = 395.2381%
  3. Check: Work backwards: 395.2381% of 21 is 3.952381 × 21 = 83.

Another method. As a proportion of part to whole: 83/21 = p/100, so p = 83 × 100 ÷ 21 = 395.2381%. Both methods always give the same answer.

In a spreadsheet: =83/21*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.
