Grade 7: Ratios and Proportional Relationships

7.RP.A

Analyze proportional relationships and use them to solve real-world and mathematical problems.

7.RP.A.1

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

7.RP.A.2

Recognize and represent proportional relationships between quantities.

7.RP.A.2.a

Fully covered
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.

7.RP.A.2.b

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

7.RP.A.2.c

Fully covered
Represent proportional relationships by equations.

7.RP.A.2.d

Fully covered
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 r is the unit rate.

7.RP.A.3

Fully covered
Use proportional relationships to solve multistep ratio and percent problems.
