How do I convert decimals into fractions using TI-30Xa and TI-30Xa Solar?

The following examples will demonstrate how to convert decimals into fractions using the TI-30Xa and TI-30Xa Solar. Please be aware that TI-30Xa Solar School Edition calculators do not have this functionality.

For Example: Convert .25 to 1/4
