Calculating Hourly Rates and Ratios

Mrs. Nelson explains how to navigate a table of equivalent ratios by finding a unit rate. Using Lynn's earnings as an example, she demonstrates how to calculate the unit rate and apply it to determine earnings for different hours worked. The lesson covers both simple and complex time calculations, emphasizing the ease of using a unit rate to solve problems involving consistent rates.

What is the main objective of the lesson on navigating a table of equivalent ratios?

• To learn how to create a table of random numbers

• To solve problems using a table and finding a unit rate

• To understand the history of ratios

• To memorize different types of tables
