Some calculators can show a decimal as a fraction if applicable. eg. 1.333333 > 1r1r3 on my calculator (hardware) representing \$1 \frac{1}{3}\$. Can the built in calculator do that? If not which (software) can?
* Whats wrong with my math?

You might be able to use Wolfram Alpha as an web application in a few days with 11.10. http://www.webupd8.org/2011/10/installepiphany320withweb.html With 11.10 you can install epiphany and have Wolfram Alpha as a web application and have it saved as an launchable icon in Unity. Hope this helps. 


Giving below link to a bash script to do the above said http://advantagebash.blogspot.in/2012/03/convertdecimaltofraction.html 


What are your constraints? Are you allowed to use online calculators? If so, just use Wolfram Alpha or one of the shortcuts to it. A search reveals Qalculate, but it's a little... pink, for my taste. Perhaps it can be themed. Also, it requires the Qt library, so expect a lot of things to be installed for just this simple program if you don't have other Qtdependent programs already on your computer.
