Proportional Relationships and Division

The video tutorial explains how to identify proportional relationships between X and Y by organizing data as Y over X. It demonstrates the process using tables, focusing on reducing fractions to determine proportionality. The first and third tables are confirmed as proportional, while the second is not. The tutorial emphasizes the importance of consistent ratios across columns to establish proportionality.

What is the first step in determining if a table represents a proportional relationship?

• Divide x by y

• Multiply x and y

• Organize it as y over x

• Organize it as x over y
