• Unit 5: Ratios and Proportions

    In this unit, we study ratios and proportions – mathematical concepts we use all the time, often without realizing it. For example,

    • At the grocery store, have you ever compared unit prices for different packages of the same type of food? That is a ratio.
    • When driving 65 mph (miles per hour) on the highway, have you ever determined how long it will take you to get to your destination? That is a proportion.
    • In sports, statisticians use proportions to predict an athlete's performance, based on what they have accomplished in the past.

    Here we explore how to write ratios, set-up and solve proportions, and apply these skills to real-world experiences.

    Completing this unit should take you approximately 8 hours.
