Lesson Summary:

In this lesson, you will learn how to add fractions when they are written as mixed numbers. The key to this process is converting the mixed numbers into improper fractions, by multiplying the denominator by the whole number and then adding the numerator. Once you have converted the mixed numbers, you can then find the least common denominator (LCD) and add the fractions together. By following these steps, you will be able to add fractions with mixed numbers quickly and easily.

Lesson Description:

How to add fractions when written as mixed numbers

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.
