A fraction represents a rational expression that is meant to convey the proportionality of one quantity to another. Pre-algebra students learn to manipulate this fact to their advantage by changing division expressions into fractions. This conversion allows for several operations, such as simplification and factorization, that reduce the complexity of a division problem in many instances. The use of this technique is made throughout virtually all subsequent mathematics courses and is of value in terms of saving time.
