Reducing Fractions: Step-by-Step Examples

The video tutorial explains how to reduce fractions using the greatest common factor (GCF). It begins with a demonstration of finding the GCF of 36 and 48, which is 12, and shows how to divide both the numerator and denominator by this factor to simplify the fraction to 3/4. An alternative method is also presented, where the fraction is reduced step-by-step by dividing by smaller factors like 2 and 3, eventually reaching the same simplified result. The tutorial emphasizes the importance of dividing both the numerator and denominator by the same number to maintain the fraction's value.
