​Understand the concept of a unit rate *a/b* associated with a ratio *a:b* with *b ≠ 0* (*b* not equal to zero), 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."*

• K1: I can write ratio notation in multiple ways. (For example, as 2:3, 2 to 3, 2/3)

• K2: I can demonstrate how ratios compare two quantities.

• K3: I can generalize that all ratios relate two quantities or measures within a given situation in a multiplicative relationship.
