• Students use ratio tables and ratio reasoning to compute unit rates associated with ratios of fractions in the context of measured quantities, e.g., recipes, lengths, areas, and speed.

• Students work together and collaboratively to solve a problem while sharing their thinking process, strategies, and solutions with the class.

• Students use unit rates to solve problems and analyze unit rates in the context of the problem.

• A fraction whose numerator or denominator is itself a fraction is called a complex fraction.

Recall: A unit rate is a rate, which is expressed as A/B units of the first quantity per 1 unit of the second quantity for two quantities A and B.
