Description

Ratios with percents are widely used in various fields, including finance, statistics, and everyday life. For example, when comparing interest rates, growth rates, or discount rates, percentages are often used. Understanding these ratios allows for better financial decision-making and data analysis.

In math education, learning to work with ratios involving percents helps students understand proportional relationships and percentage calculations. For instance, if the sales tax in a state is 6% and 8% in another state, what is the ratio of sales taxes? The ratio becomes 6%:8%, which simplifies to 3:4.

Teacher’s Script: "If a line of shirts is discounted by 20% and a line of shoes is discounted by 50%, what is the ratio of the two discounts? We can create ratios that involve percents. This becomes 20%:50%, which simplifies to 2:5."
