This math topic focuses on practicing the skill of finding the lowest common denominator (LCD) for comparison between two fractions. It challenges students to identify the best LCD that would allow them to directly compare different pairs of fractions. The problems present fractions with varied denominators, and students must choose the correct LCD from a list of options. The topic is designed as a practical exercise to strengthen understanding of manipulating and comparing fractions in mixed forms where denominators need to be modified.
