Lesson Summary:

In this video, you will learn how to add fractions with a common denominator. Just like how you would add cats and more cats together, or apples and more apples together, you can add fractions that have the same denominator. You keep the denominator the same and add the numerator. You will go through several examples, and learn how to simplify your answer into the simplest form. By the end of the video, even the most complicated fractions will seem like a breeze to add!
