In this lesson, you will learn how to add fractions with the same or different denominators. The key is finding a common denominator and adding the numerators while keeping the denominator the same. If the fractions have different denominators, you will need to find the lowest common denominator (LCD) by listing out the multiples and then converting the fractions to have the same denominator before adding them together. The result may be an improper fraction, which can be converted to a mixed number.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
