# 6.RP.A.2

Understand the concept of a unit rate $a/b$ associated with a ratio $a:b$ with $b \neq 0$, 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.”Expectations for unit rates in this grade are limited to non-complex fractions.
