Lesson Summary:

This lesson teaches how to solve a proportion with a variable on both sides without relying on the cross-multiplication method. Instead, the lesson emphasizes the importance of finding the least common multiple or denominator to eliminate the rational terms. By multiplying each term by the least common multiple, the fractions are eliminated, and the variables can be solved on one side. This lesson also provides tips on avoiding common mistakes that students often make while solving such problems.

Lesson Description:

How to solve a proportion with a variable on both sides

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.
