Understanding Ratios and Percents

This video tutorial covers Module 1 Lesson 24 of Eureka Math, focusing on understanding percents as part-to-whole ratios and rates where the whole is 100. The lesson includes exercises on modeling percents with examples like Robb's fruit farm, a granola bar, shaded regions, and student grades. It also covers converting between percents, decimals, fractions, and ratios. The tutorial concludes with an exit ticket exercise and encourages students to participate in a live chat for further practice.
