Lesson Summary:

In this lesson, we explore the process of adding fractions with unlike denominators. The key is to find the least common denominator, and there are multiple ways to do so. Once we have the least common denominator, we extend the fraction bar to multiply the top and bottom of each fraction by the necessary number to achieve the common denominator. After that, we simply add the numerators and simplify if possible, either by reducing or changing the fraction to a mixed number. This lesson provides several examples to help solidify this concept.

Lesson Description:

A second part to a lesson on adding fractions that do not have a common denominator.
