This math topic involves the practice of finding missing numerators to complete equivalent fractions. Each problem presents a multiplication of a simple fraction by another fraction, resulting in a fraction with an unknown numerator. The students are provided with multiple choice answers. These exercises are part of an introductory unit on comparing fractions, aimed at reinforcing the concept of equivalent fractions by manipulating numerators while the denominators are transformed. This level of proficiency focuses on one-digit numerators with straightforward scalar transformations to deepen understanding of fraction equivalence.
