How to work it out

  1. Divide the part by the whole: 100 ÷ 21 = 4.761905
  2. Multiply by 100: 4.761905 × 100 = 476.1905%
  3. Check: Work backwards: 476.1905% of 21 is 4.761905 × 21 = 100.

Another method. As a proportion of part to whole: 100/21 = p/100, so p = 100 × 100 ÷ 21 = 476.1905%. Both methods always give the same answer.

In a spreadsheet: =100/21*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.

What the result means

100 is more than the whole amount (4.762 times as much) of 21. 100 goes past 21 by 79, which is another 376.1905% on top of the whole.

Targets: selling 100 items against a target of 21 means reaching 476.1905% of the target, beating it by 376.1905%.

Turning it around

If you know that 100 is 476.1905% of a number, you can get that number back: 100 ÷ 4.761905 = 21. And 21 as a percentage of 100 is 21%, a different answer, because the whole has changed.
