Nicole,
Yesterday I went to the lunch counter and bought onequarter of a pizza for lunch. I went to the lunch room and cut it into three parts to share with two of my friends. What I ended up eating was onethird of onequarter of a pizza. What fraction of the whole pizza did I eat?
Imagine that four people did exactly what I did. Each of us took onequarter of the pizza and cut it in three. Thus the entire pizza was cut into 4 3 = 12 pieces, and I ate one piece. Thus I ate onetwelfth of the pizza. Hence onethird of onequarter is onetwelfth.
