Finding the Least Common Denominator and Comparing Fractions

This video tutorial by Make Steve Tutorials teaches how to find a common denominator for fractions, a crucial step for comparing or adding them. It explains that multiplying or dividing both the numerator and denominator by the same number does not change the fraction's value. The video provides several examples of comparing fractions by finding the least common multiple and adjusting the fractions accordingly. It concludes with a call to action for viewers to subscribe and comment.
