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.

What is the first step in solving the problem using cross reducing?

What common factor do six and nine share that allows them to be reduced?

What are the factors of seven and four, and do they have any common factors?

What is the new expression after reducing the fractions?

How do you verify that the final answer is in simplest form?
