This Instructional Activity is a part of the Lesson 2, Unit 9, Grade 6. In this activity, students review work with percentages and arithmetic from earlier units. It also gives them a framework for thinking about the next activity. Students have to decide how to treat a situation in which ratios are approximately equivalent. People can only be reported in whole number quantities, and students need to decide how to round numbers appropriately as a result.
