Interpret and compute quotients of fractions, and solve word problems involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem. <span class='clarification'>For example, create a story context for (2/3) \div (3/4) and use a visual fraction model to show the quotient; use the relationship between multiplication and division to explain that (2/3) \div (3/4) = 8/9 because 3/4 of 8/9 is 2/3. (In general, (a/b) \div (c/d) = ad/bc.) How much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 3/4-cup servings are in 2/3 of a cup of yogurt? How wide is a rectangular strip of land with length 3/4 mi and area 1/2 square mi? </span>
