Simplifying Fractions and GCF

The video tutorial explains how to simplify improper fractions, where the numerator is greater than or equal to the denominator. It provides two examples: simplifying 72/8 and 33/11. The process involves identifying the greatest common factor and dividing both the numerator and denominator by it to achieve the simplest form. The tutorial demonstrates multiple methods to simplify fractions, emphasizing the importance of recognizing common factors for efficient simplification.
