Difference between equivalent fractions and equations

The video tutorial explains the process of multiplying fractions and equations by the least common multiple (LCM) to either create equivalent fractions or eliminate denominators. It highlights the importance of using LCM to add fractions by achieving common denominators and contrasts this with eliminating denominators in equations. The tutorial also discusses the implications of multiplying both the numerator and denominator by the LCM, emphasizing the creation of equivalent equations without simplifying the problem.
