Water and Cornmeal Ratios

This video tutorial by Mr. Holcomb covers lesson nine on tables of equivalent ratios. It begins with an introduction to the concept of equivalent ratios using a paper mache example. The lesson continues with Xavier's web design job, illustrating how to use ratio tables to calculate earnings. The tutorial then explores a cornmeal juice exercise to further understand ratio tables and equivalent ratios. Finally, it concludes with a goldfish tank exercise, demonstrating how to calculate water needs for goldfish using ratio tables. The lesson emphasizes the importance of understanding and applying equivalent ratios in various contexts.
