Understanding Ratios and Their Applications

Misty introduces ratios and proportions, explaining their definitions and uses in math. She provides examples from a math textbook, including comparing quantities like snails and fish, and using recipes to illustrate writing and interpreting ratios. Misty also discusses patterns in ratios using tables and models real-life scenarios, such as mixing paint, to demonstrate practical applications. Throughout, she emphasizes the use of calculators for complex calculations and encourages students to join her online meetings for further assistance.
