Description

This activity challenges students to use proportions to estimate how many 30-minute television shows can be recorded on a VCR tape using the SP (standard play) and the EP (extended play) modes. The activity begins with the observation that fractions, ratios, and proportions are used in comparison shopping, making scale models, and describing population densities. The Hint suggests that students begin by calculating how many half-hour shows could be recorded on the SP setting. Related questions ask students to use data tables to estimate the viewing preferences of different demographic groups. Answers to all questions are provided, as are links to additional resources.
