This document is from a mathematics lesson on equivalent ratios. It includes the homework assignment, aims of the lesson which are finding equivalent ratios given a total quantity. It also provides examples and discussion questions about using proportions and equivalent ratios to find missing values in tables. The examples ask students to determine how backpacks weights are proportional to hikers' weights using ratios.

Discussion Questions:
Example 1:
• How did you find the missing values
in the third column of the table?
• Based on the table, is the backpack
weight proportional to the hiker's
weight? How do you know?
• Would these quantities always be
proportional to each other?
