How to work it out

  1. Divide the part by the whole: 30 ÷ 8 = 3.75
  2. Multiply by 100: 3.75 × 100 = 375%
  3. Check: Work backwards: 375% of 8 is 3.75 × 8 = 30.

Another method. As a proportion of part to whole: 30/8 = p/100, so p = 30 × 100 ÷ 8 = 375%. Both methods always give the same answer.

In a spreadsheet: =30/8*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

30 is more than the whole amount (3.75 times as much) of 8. 30 goes past 8 by 22, which is another 275% on top of the whole.

Targets: selling 30 items against a target of 8 means reaching 375% of the target, beating it by 275%.

Turning it around

If you know that 30 is 375% of a number, you can get that number back: 30 ÷ 3.75 = 8. And 8 as a percentage of 30 is 26.6667%, a different answer, because the whole has changed.
