Defining Percentages Using Ratios

This video tutorial explains the concept of ratios and how they relate to percents. It begins by defining ratios, particularly part-to-total ratios, and demonstrates how to simplify them. The lesson then transitions to percents, clarifying that a percent is a specific type of ratio where the total is always 100. The tutorial emphasizes the importance of understanding that 60% is not the same as the number 60, and provides examples of how to express and simplify percent ratios. By the end of the lesson, viewers will understand how to define percents using ratios and simplify them effectively.
