Understanding Ratios and Proportions

This video tutorial introduces the concept of ratios, using examples like candies and cake recipes to explain how ratios are used to compare quantities. It covers different types of ratios, such as part-to-part and part-to-whole, and demonstrates how to simplify ratios using the highest common factor. The tutorial concludes with encouragement to explore more learning resources.
