Instructor Overview

Students use percents greater than 100% to solve problems about rainfall, revenue, snowfall, and school attendance.

Key Concepts

Percents greater than 100% are useful in making comparisons between the values of a single quantity at two points in time. When a later value is more than 100% of an earlier value, it means the quantity has increased over time. This percent comparison can be used to find unknown values, whether the earlier or later value is unknown.

Goals and Learning Objectives

  • Understand the meaning of a percent greater than 100% in real-world situations.
  • Use percents greater than 100% to interpret situations and solve problems.
