Fractions are another way to cite percentages. How many people handed in their homework today? 18/20....9/10 of the people did their homework! How many people LIKE something (survey)? 99/100 people like crest toothpaste (made up that statistic). How many peices of chocolate out of all the peices of candy did you recieve for Halloween?
if you're musically inclined--- music notes! You have your whole note, half note, quarter note, eighth note.... and they all add up to each other of course. so two half notes are the same length as a whole note.
