What do you need to know to solve a proportion

This video tutorial covers essential skills for success in the course, focusing on solving proportions and linear equations. It explains the concept of proportions as fractions equal to each other and discusses various methods for solving linear equations, including one-step, two-step, and multi-step equations. The tutorial emphasizes the importance of simplifying expressions and introduces the preferred method of using the least common multiple (LCM) to solve proportions. Additionally, it addresses the common method of cross multiplication, highlighting its benefits and potential pitfalls.
