How to work it out

  1. Divide the part by the whole: 45 ÷ 12 = 3.75
  2. Multiply by 100: 3.75 × 100 = 375%
  3. Check: Work backwards: 375% of 12 is 3.75 × 12 = 45.

Another method. As a proportion of part to whole: 45/12 = p/100, so p = 45 × 100 ÷ 12 = 375%. Both methods always give the same answer.

In a spreadsheet: =45/12*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 (3.75 times as much) of 12. 45 goes past 12 by 33, which is another 275% on top of the whole.

Targets: selling 45 items against a target of 12 means reaching 375% of the target, beating it by 275%.

Turning it around

If you know that 45 is 375% of a number, you can get that number back: 45 ÷ 3.75 = 12. And 12 as a percentage of 45 is 26.6667%, a different answer, because the whole has changed.
