Formatting ratios
To show the result of division as a ratio, you can use a custom number format. For example, the current ratio is current assets divided by current liabilities. Typically, this ratio is shown as x:1, or like this

The custom number format applied to the current ratio is set by using Format>Cells>Number

This format works because the current ratio is always shown compared to one. If you want to show a ratio, but the denominator is unknown, you can use tip81 from The Spreadsheet Page.

Thank you for making this function so simple and so easy. I was able to perform a task which would normally have taken me an hour to research in only a matter of five minutes. Much appreciated!

Another amazing formatting trick: type a ratio, e.g. 6/5, and precede it by a 0, that is: 0 6/5. See what Excel displays.

Hi, this custom type does not exist in Excel 2007; any idea how to display a ration in this version?

You have to create custom types yourself (although MS creates some to get you started). Choose Custom and type this in the textbox.

Here is another way of doing this

I came up with this when wanting to show the ratio between two numbers
=”1:”&(A1/B1)
then refined it to show the ratio to only two decimal places
=”1:”&ROUND(A1/B1, 2)
