How to work it out

  1. Divide the part by the whole: 55 ÷ 30 = 1.833333
  2. Multiply by 100: 1.833333 × 100 = 183.3333%
  3. Check: Work backwards: 183.3333% of 30 is 1.833333 × 30 = 55.

Another method. As a proportion of part to whole: 55/30 = p/100, so p = 55 × 100 ÷ 30 = 183.3333%. Both methods always give the same answer.

In a spreadsheet: =55/30*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

55 is more than the whole amount (1.833 times as much) of 30. 55 goes past 30 by 25, which is another 83.3333% on top of the whole.

Targets: selling 55 items against a target of 30 means reaching 183.3333% of the target, beating it by 83.3333%.

Turning it around

If you know that 55 is 183.3333% of a number, you can get that number back: 55 ÷ 1.833333 = 30. And 30 as a percentage of 55 is 54.5455%, a different answer, because the whole has changed.
