Grade 6
Domain Ratios and Proportional Relationships
Cluster Understand ratio concepts and use ratio reasoning to solve problems.
Standard 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. <span class='clarification'>For example, &ldquo;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.&rdquo; &ldquo;We paid $\$75$ for $15$ hamburgers, which is a rate of $\$5$ per hamburger.&rdquo;</span><span class='footnote'>Expectations for unit rates in this grade are limited to non-complex fractions.</span>
