Standard: 7.RP.A.2.B
Domain: Ratios & Proportional Relationships
Theme: Analyze proportional relationships and use them to solve real-world and mathematical problems
Description: Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
What is the unit rate for a pound of seed?
A
$3.50
B
$1.75
C

Standard: 7.RP.A.1
Domain: Ratios & Proportional Relationships
Theme: Analyze proportional relationships and use them to solve real-world and mathematical problems
Description: Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction (1/2)/(1/4) miles per hour, equivalently 2 miles per hour.
