This math topic focuses on practicing the skills of completing equivalent fractions by finding the missing denominator. It employs single-digit equations within the context of introductory fraction comparison. Each question provides a scenario of multiplying one fraction to derive an equivalent fraction, and the learner must determine what the denominator should be to make the two fractions equivalent. This is a Level 2 worksheet, suggesting a progression from more basic exercises, and is part of a broader unit introducing concepts of comparing fractions.
