Overview of Ratios and Proportions

Ratios and proportions are fundamental concepts in mathematics that help us understand and compare quantities. They are essential for students in grades 5–9, serving as building blocks for advanced topics like algebra, geometry, and real-world problem-solving.

Understanding Ratios

• Definition: A ratio is a comparison of two quantities showing the relative sizes of two values.

• Representation: Ratios can be expressed in three ways:

  • Using the colon symbol

  • As a fraction

  • In words

Understanding Proportions

• Definition: A proportion is an equation stating that two ratios are equal.

• Purpose: Proportions allow us to solve for unknown values and make predictions based on known relationships.

Key Concepts

• Equivalent Ratios: Ratios that represent the same relationship.

• Cross-Multiplication: A method to solve proportions by multiplying across the equals sign.

• Unit Rates and Rates: Understanding ratios in terms of per-unit measurements (e.g., miles per hour).
