Title: Trello card #549: Ordering and comparing decimals

This is my first exercise. Any input/suggestions/changes, please let me know! (I know there is another exercise submission for this card, but I thought it would be a good place to start practicing writing exercises.)

Corresponds to Trello card #549: Ordering decimals and comparing decimals.
