INTRODUCTION TO FRACTIONS (CONTINUED)
|Dividing fractions means determining how many smaller pieces there are in a larger piece.|
--- / --- = 2
Means: one-half divided by one-fourth is 2
This means there are 2 one-fourth 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
|1/6 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
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 one-fourth boards in a half-board and that there are two one-sixth boards in a one-third board!
So now, let's begin!
