Understanding Complex Fractions

The video tutorial explains how to simplify complex fractions by recognizing that a fraction bar represents division. It demonstrates converting a division problem into a multiplication problem using the reciprocal of the divisor. The tutorial further simplifies the expression by identifying and canceling common factors through prime factorization, resulting in a simplified fraction. The process is broken down into clear steps to make it easy to understand.
