6.AT.A.2: Represent and use unit rates, written as fractions (a/b, b ≠ 0) with whole number numerators and denominators, in context. a. Use unit rate language in the context of a ratio relationship (e.g., “The 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.”) b. Solve unit rate problems, for example those involving unit pricing and constant speed (e.g., “If it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed?”).
