How to work it out

  1. Divide the part by the whole: 15 ÷ 8 = 1.875
  2. Multiply by 100: 1.875 × 100 = 187.5%
  3. Check: Work backwards: 187.5% of 8 is 1.875 × 8 = 15.

Another method. As a proportion of part to whole: 15/8 = p/100, so p = 15 × 100 ÷ 8 = 187.5%. Both methods always give the same answer.

In a spreadsheet: =15/8*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

15 is more than the whole amount (1.875 times as much) of 8. 15 goes past 8 by 7, which is another 87.5% on top of the whole.

Targets: selling 15 items against a target of 8 means reaching 187.5% of the target, beating it by 87.5%.

Turning it around

If you know that 15 is 187.5% of a number, you can get that number back: 15 ÷ 1.875 = 8. And 8 as a percentage of 15 is 53.3333%, a different answer, because the whole has changed.
