Chapter 5: Ratios and Proportions
What you learned before:
1. Graph ordered pairs in all four quadrants of a coordinate plane.
2. Understand ratios and describe ratio relationships
3. Compare ratios using tables
4. Use ratio reasoning to convert measurement units
5. Understand rates and ratios
6. Understand parttopart and parttototal(whole) relationships
In this chapter, you will learn to:
1. Find unit rates associated with ratios of fractions, areas, and other quantities in like or different units.
2. Decide whether two quantities are proportional using ratio tables and coordinate graphs.
3. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions.
4. Represent proportional relationships with equations.
5. Explain what a point (x, y ) means on a proportional graph in context,particularly (0, 0) and (1, r ), where r is the unit rate.
6. Use proportionality to solve ratio problems.
