Understanding Implied Information in Part to Total Ratios

This video tutorial teaches how to identify implied information in part to total ratios by using diagrams. It begins with an introduction to ratios, explaining the different types, and focuses on part to total ratios. The tutorial highlights common mistakes and uses a scenario to demonstrate how to uncover hidden information. A tower diagram is introduced as a tool to visualize and find missing information, leading to the exploration of part to part ratios. By the end, viewers learn to analyze and interpret ratios beyond the initial information given.
