Converting Fractions to Percentages

This video tutorial covers the concept of percents, explaining how they are ratios comparing numbers to 100. It uses real-life examples, such as basketball free throw ratios, to illustrate how to convert fractions to percents. The tutorial also demonstrates using grid models and percent bar models to visualize and calculate percents. Additionally, it introduces benchmarks as a tool for simplifying percent calculations and provides practice problems to reinforce the concepts learned.
