In this math tutorial, you will learn how to reduce fractions using the prime factoring method. The narrator, a math teacher, of the video begins by defining what prime numbers are. This is important to know. When reducing fractions you need to reduce both the numerator and the denominator down to numbers that cannot be reduced by any other numbers but 1 and itself (prime numbers). The method the video teaches is to find the prime factors of both numerator and the denominator to simplify the reduction of a fraction by canceling out like numbers such as 2 and 3. The video also illustrates two methods for prime factoring a number such as the tree method and the ladder method. After watching this tutorial you will be able to understand how to effectively reduce fractions.
