Equivalent Fractions and Common Multiples

The video tutorial explains how to find a common denominator to compare fractions. It begins by identifying the need for a common denominator and demonstrates how to find it by listing multiples of the denominators. The tutorial then shows how to convert fractions to equivalent fractions with the common denominator. Finally, it compares the fractions to determine which is larger.
