Cross-Reducing (Example)

The video tutorial demonstrates how to solve a multiplication problem involving fractions using the cross-reducing method. It begins by identifying common factors between numerators and denominators of different fractions to simplify them. The tutorial then shows how to multiply the simplified fractions and verify that the result is in its simplest form.
