How to work it out

  1. Divide the part by the whole: 16 ÷ 81 = 0.197531
  2. Multiply by 100: 0.197531 × 100 = 19.7531%
  3. Check: Work backwards: 19.7531% of 81 is 0.197531 × 81 = 16.

Another method. As a proportion of part to whole: 16/81 = p/100, so p = 16 × 100 ÷ 81 = 19.7531%. Both methods always give the same answer.

In a spreadsheet: =16/81*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

16 is between a tenth and a quarter of 81. The part that is left, 65, is the other 80.2469%.
