Exploring Ratios and Their Applications

The video tutorial introduces the concept of ratios, explaining how to compare two or more quantities using different methods. It covers part-to-part, part-to-whole, and whole-to-part comparisons using shapes like triangles, circles, and squares. The tutorial emphasizes not simplifying ratios and provides various ways to express them, such as using colons, words, or fractions.
