Lesson Summary:

In this lesson, we learn how to simplify algebraic complex fractions using two different methods. Method one involves simplifying the numerator and denominator of the complex fraction and then multiplying the numerator by the reciprocal of the denominator. Method two involves finding the least common denominator of the fractions in the numerator and denominator, multiplying both the numerator and denominator by it, and then simplifying. These methods are used to simplify fractions with variables and numbers, making them more manageable to work with.

Lesson Description:
