This video tutorial from Math Antics introduces the concept of ratios, explaining them as a comparison of two numbers by division. It highlights the difference between ratios and fractions, emphasizing their real-world applications. The video also introduces rates as a type of ratio involving time and demonstrates how to convert rates into unit rates for easier comparison. Through examples, viewers learn how ratios and rates are used in everyday situations, such as in recipes, screen dimensions, and speed measurements.
