Understanding Ratios and Rates

This video tutorial covers the concepts of ratios and rates, explaining how ratios compare two or more numbers or measurements and how rates are ratios with different units. It provides examples of reducing fractions to their lowest terms, converting ratios to fractions, decimals, and percents, and simplifying ratios using the greatest common factor (GCF). The video also includes practical problems to demonstrate the application of these concepts in real-world scenarios.
