Lesson Summary:
In this lesson, the instructor teaches how to add fractions with different denominators by finding a common denominator. The concept of finding the least common denominator is emphasized, and the instructor goes through several examples, showing the steps involved in finding the common denominator and converting each fraction to an equivalent fraction. The process of adding the fractions is then demonstrated, and the importance of reducing the fraction to its simplest form is discussed. This is part 1 of a two-part series on how to add fractions with unlike denominators.
Lesson Description:
Learn how to add fractions that do not have a common denominator.

Staff Review
This lesson goes over a very important skill in finding common denominators to add fractions with unlike denominators. This is a great tutorial with several good example problems explained in detail. If you do not know how to find the least common denominator or how to add fractions with the same denominator, look through some older lessons that show these skills.
