# Grade 7: Ratios and Proportional Relationships

#### 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.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.
