decimal to fraction (just display)

hey, how do I go about taking a two decimal place decimal number and showing it as a fraction? Just in the GUI.Label so value / value would still be fine. :D

Multiply it by 100, and then put it over 100.

For example: 0.77 becomes 77/100


string Frac = Convert.ToInt32(MyDecimal*100).ToString()+"/100";

You can attempt to reduce it to it's lowest common denominator if you wish, but thats more work. Not much more, but more.
