Understand ratio concepts and use ratio reasoning to solve problems. 11

- 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."*7 - 2.Understand the concept of a unit rate
*a/b*associated with a ratio*a:b*with*b ≠ 0*, and use rate language in the context of a ratio relationship.*For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger."*61 - 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. 9
