Finding Missing Numbers in Equivalent Fractions

This video tutorial focuses on finding missing numbers in equivalent fraction pairs. It begins with an introduction to the concept, followed by two examples. The first example demonstrates how to solve 2/3 = 4/? by multiplying both the numerator and denominator by the same number. The second example shows how to solve 1/4 = ?/16 using a similar method. The video concludes with encouragement for students to practice these skills.
