In this Grade 7 lesson from enVision Mathematics Chapter 2, students learn how to find and apply unit rates by dividing ratios to a per-unit value, and use equivalent ratios to compare rates and solve multi-step problems. Students practice calculating unit rates in real-world contexts such as hourly pay, consumption over time, and speed, then use those rates to make comparisons and draw conclusions. The lesson builds foundational understanding of how ratios, rates, and unit rates are interconnected tools for proportional reasoning.
Section 1
Ratios
A ratio is a type of quotient used to compare two numerical quantities. The ratio of to is written . A ratio can be expressed as a decimal instead of a common fraction.
Section 2
Understanding Rates and Unit Rates
A ratio compares two quantities, often of the same kind.
A rate is a special type of ratio that compares quantities with different units (like miles and gallons, or dollars and hours).
