How to work it out

  1. Divide the part by the whole: 45 ÷ 18 = 2.5
  2. Multiply by 100: 2.5 × 100 = 250%
  3. Check: Work backwards: 250% of 18 is 2.5 × 18 = 45.

In a spreadsheet: =45/18*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

45 is more than the whole amount (2.5 times as much) of 18. 45 goes past 18 by 27, which is another 150% on top of the whole.

Targets: selling 45 items against a target of 18 means reaching 250% of the target, beating it by 150%.

Turning it around
