Cross Reducing and Multiplying Fractions

This video tutorial explains how to simplify fractions by cross reducing before multiplying. It begins with an introduction to the concept of cross reducing, followed by a step-by-step demonstration using the fractions 4/7 and 14/36. The process involves finding the greatest common factor (GCF) of the numerators and denominators across the fractions, simplifying them, and then multiplying the simplified fractions to obtain the final result of 2/9.
