## 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.

Which of the following sets of ordered pairs shows a proportional relationship?

{(4, 2), (8, 3), (12, 4), (16, 5)}

{(1, 2), (2, 3), (3, 4), (4, 5)}

{(10, 2), (20, 4), (30, 6), (40, 8)}
