Comparing Prices and Ratios

The video tutorial covers the use of ratios to compare speeds and prices. It begins with an introduction to ratios, followed by estimating quotients for given divisions. The tutorial then explores treadmill speed comparisons using ratios, and concludes with an analysis of bean prices to determine the best deal. The focus is on understanding equivalent ratios and making informed decisions based on unit rates.
