In this lesson on multiplying fractions, Professor Perez teaches Charlie three different ways to approach the same problem. The first way requires more steps, but the second and third methods are faster and involve reducing before multiplying. The lesson also covers reducing fractions and how to approach problems with multiple fractions. By the end of the lesson, Charlie has learned how to multiply fractions quickly and efficiently.
