Simplifying Fractions with Factor Trees

The video tutorial introduces factor trees and demonstrates how to use them to simplify fractions. It begins with an explanation of factor trees and their purpose, followed by examples of creating factor trees for numbers like 36, 24, and 100. The tutorial then applies factor trees to simplify fractions, using examples such as 18/27, 4/24, and 225/100. The process involves breaking down numbers into their prime factors, identifying common factors, and simplifying the fractions accordingly.
