How to work it out

  1. Divide the part by the whole: 8 ÷ 63 = 0.126984
  2. Multiply by 100: 0.126984 × 100 = 12.6984%
  3. Check: Work backwards: 12.6984% of 63 is 0.126984 × 63 = 8.

Another method. As a proportion of part to whole: 8/63 = p/100, so p = 8 × 100 ÷ 63 = 12.6984%. Both methods always give the same answer.

In a spreadsheet: =8/63*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
