How to work it out

  1. Divide the part by the whole: 4 ÷ 1 = 4
  2. Multiply by 100: 4 × 100 = 400%
  3. Check: Work backwards: 400% of 1 is 4 × 1 = 4.

Another method. As a proportion of part to whole: 4/1 = p/100, so p = 4 × 100 ÷ 1 = 400%. Both methods always give the same answer.

In a spreadsheet: =4/1*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

4 is more than the whole amount (4 times as much) of 1. 4 goes past 1 by 3, which is another 300% on top of the whole.

Targets: selling 4 items against a target of 1 means reaching 400% of the target, beating it by 300%.

Turning it around

If you know that 4 is 400% of a number, you can get that number back: 4 ÷ 4 = 1. And 1 as a percentage of 4 is 25%, a different answer, because the whole has changed.
