How to work it out

  1. Divide the part by the whole: 99 ÷ 90 = 1.1
  2. Multiply by 100: 1.1 × 100 = 110%
  3. Check: Work backwards: 110% of 90 is 1.1 × 90 = 99.

Another method. As a proportion of part to whole: 99/90 = p/100, so p = 99 × 100 ÷ 90 = 110%. Both methods always give the same answer.

In a spreadsheet: =99/90*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

99 is more than the whole amount (1.1 times as much) of 90. 99 goes past 90 by 9, which is another 10% on top of the whole.

Targets: selling 99 items against a target of 90 means reaching 110% of the target, beating it by 10%.

Turning it around

If you know that 99 is 110% of a number, you can get that number back: 99 ÷ 1.1 = 90. And 90 as a percentage of 99 is 90.9091%, a different answer, because the whole has changed.
