INTRODUCTION TO FRACTIONS (CONTINUED)
DIVIDING FRACTIONS
Dividing fractions means determining how many smaller pieces there are in a larger piece.
For example:


1 1
 /  = 2
2 4
Means: onehalf divided by onefourth is 2
This means there are 2 onefourth pieces of pizza in a half pizza.


Unit 4 shows you how to do this division.
Here's another way to look at fractions. Imagine that you have a board and you want to cut it into halves, thirds, fourths, sixths, and fifths. Here is what those board fractions look like:
<===================one whole board!!====================> 
1/4 board  1/4 board 
1/4 board  1/4 board 
1/3 board  1/3 board
 1/3 board 
1/6 board  1/6 board  1/6 board 
1/6 board  1/6 board  1/6 board 
1/5 board  1/5 board  1/5 board  1/5 board 
1/5 board 
Notice that the 2 1/4th boards add up to a half board and that the 2 1/6 boards add up to a 1/3 board.
This means that there are 2 onefourth boards in a halfboard and that there are two onesixth boards in a onethird board!
So now, let's begin!
