Comparing Ratios Using Tables

This video tutorial covers lesson 6.3a on using tables to compare ratios. It explains how to write equivalent ratios and use tables to compare them, using examples like the ratios of pineapple to orange juice in mixtures made by Bob and Dave. The video demonstrates how to create ratio tables, compare fractions with common denominators, and analyze part-to-whole relationships. It concludes with a preview of the next lesson, which will focus on comparing ratios using multiplication and division.

What is the purpose of using tables in ratio comparison?

• To calculate the sum of ratios

• To subtract one ratio from another

• To create equivalent ratios for comparison

• To find the greatest common divisor

How do you write a ratio using a colon?

• As a subtraction

• As a multiplication

• As a division

• As a comparison
