In this lesson on multiplying fractions, Professor Perez uses both number lines and arithmetic to help students understand the concept. He explains that multiplication with fractions is essentially repeated addition, and shows how to add fractions with different denominators. He also demonstrates how to write whole numbers as fractions to multiply with fractions, and emphasizes the importance of reducing fractions before multiplying.
