Exploring Equivalent Fractions in 5th Grade Math

In this video, Mr. J introduces the concept of equivalent fractions, emphasizing their importance in various mathematical operations and everyday life. He explains the main rule for creating equivalent fractions: whatever operation is performed on the numerator must also be performed on the denominator, using either multiplication or division. The video includes examples to illustrate this rule and exercises to identify non-equivalent fractions. The session concludes with a prompt for viewers to attempt a mastery check to reinforce their understanding.

What is the primary rule for creating equivalent fractions?
