This task serves several purposes that, taken together, strengthen and develop the students' ability to perform a variety of increasingly complex arithmetic operations involving fractions. This task requires students to complete a series of steps in order to find a solution, and because they need to analyze constraints, it addresses some aspects of mathematical modeling. Students must first add fractions with familiar but unlike denominators, which is a skill developed in the 5th grade. Then students need to divide fractions by fractions.
