Notes on Lowest Terms

 

A fraction is said to be in Lowest Terms when the GCF of its numerator and denominator is 1.  It can not be reduced to a smaller numerator and denominator equivalent fraction.

 

The two methods for reducing a fraction to lowest terms are listed below:

 

Method 1:  Keep dividing both the numerator and denominator by a common factor until you can find no more common factors.

Since there are no more common factors between 4 and 5 (numerator and denominator), is the lowest terms.

Method 2:

  1. Find the GCF of the numerator and denominator

 

 
 

 

 

 


  1. Divide both the numerator and denominator by the GCF
