Unit 3: Ratio and Proportional relationships
Unit Description


  • Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units;

  • Recognize and represent proportional relationships between quantities;

  • Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin;

  • Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships;

  • Represent proportional relationships by equations.  For example, if total cost t is 
    proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn

  • Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where is the unit rate; and 

  • Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
