How to work it out

  1. Divide the part by the whole: 84 ÷ 42 = 2
  2. Multiply by 100: 2 × 100 = 200%
  3. Check: Work backwards: 200% of 42 is 2 × 42 = 84.

Another method. As a proportion of part to whole: 84/42 = p/100, so p = 84 × 100 ÷ 42 = 200%. Both methods always give the same answer.

In a spreadsheet: =84/42*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

84 is more than the whole amount (2 times as much) of 42. 84 goes past 42 by 42, which is another 100% on top of the whole.

Targets: selling 84 items against a target of 42 means reaching 200% of the target, beating it by 100%.

Turning it around

If you know that 84 is 200% of a number, you can get that number back: 84 ÷ 2 = 42. And 42 as a percentage of 84 is 50%, a different answer, because the whole has changed.
