Look for and express regularity in repeated reasoning. ||Common Core Mathematics||Grade 6||Mathematical Practices|||6.RP.1. Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. For example, “”The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak.”” “”For every vote candidate A received, candidate C received nearly three votes.””||Common Core Mathematics||Grade 6||Ratios And Proportional Relationships||Understand Ratio Concepts And Use Ratio Reasoning To Solve Problems|||6.RP.3. Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.||Common Core Mathematics||Grade 6||Ratios And Proportional Relationships||Understand Ratio Concepts And Use Ratio Reasoning To Solve Problems|||Mathematical Practices: 1.

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.||Common Core Mathematics||Grade 7||Ratios And Proportional Relationships||Analyze Proportional Relationships And Use Them To Solve Real-World And Mathematical Problems|||7.RP.2.
