How to convert a whole number into a mixed number?
Is this what you need?

If that didn't help, please post an example of what you're trying to do.
Example: 5 - 2 1/3 how do you get the answer? On my example it says the answer is 2 2/3
You seem to understand this now -- judging from your later post.
5 = 4 3/3
4 3/3 - 2 1/3 = 2 2/3
