M.6.R.RP.1PriorityA unit rate is one particular way of describing a ratio, so the idea of a ratio comes first.Explain the concept of a ratio and efficiently, flexibly, and accurately use ratio language to describe a ratio relationship between two quantities.

M.6.R.RP.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.
