This math topic focuses on understanding and calculating equivalent fractions. It includes practicing the skill of multiplying fractions by a form of one (like \( \frac{2}{2}, \frac{3}{3} \)) to find the equivalent fractions. Problems present fractional expressions and require finding the result of the multiplication as an equivalent fraction. Part of an introductory unit on comparing fractions, these problems are instrumental in reinforcing the concept of equivalency in fractions.
