Exploring Rates and Ratios in Edpuzzle

The video tutorial covers lesson 6.3 on using ratios and rates to solve word problems. It includes examples such as calculating the number of cakes baked over weeks, ticket costs, and ratios of children to adults. The tutorial explains two methods: using unit rates and equivalent ratios. It also introduces the concept of proportions and provides practice problems. The lesson concludes with a preview of the next module on cross multiplication.
