How to work it out

  1. Divide the part by the whole: 2 ÷ 1 = 2
  2. Multiply by 100: 2 × 100 = 200%
  3. Check: Work backwards: 200% of 1 is 2 × 1 = 2.

Another method. As a proportion of part to whole: 2/1 = p/100, so p = 2 × 100 ÷ 1 = 200%. Both methods always give the same answer.

In a spreadsheet: =2/1*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

2 is more than the whole amount (2 times as much) of 1. 2 goes past 1 by 1, which is another 100% on top of the whole.

Targets: selling 2 items against a target of 1 means reaching 200% of the target, beating it by 100%.

Turning it around

If you know that 2 is 200% of a number, you can get that number back: 2 ÷ 2 = 1. And 1 as a percentage of 2 is 50%, a different answer, because the whole has changed.
