How to work it out

  1. Divide the part by the whole: 21 ÷ 19 = 1.105263
  2. Multiply by 100: 1.105263 × 100 = 110.5263%
  3. Check: Work backwards: 110.5263% of 19 is 1.105263 × 19 = 21.

Another method. As a proportion of part to whole: 21/19 = p/100, so p = 21 × 100 ÷ 19 = 110.5263%. Both methods always give the same answer.

In a spreadsheet: =21/19*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
