Chapter 8: Divide Fractions
5.NF.B.3 - Interpret a fraction as division of the numerator by the denominator a/b. Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
5.NF.B.7 - Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.
Interpret division of a unit fraction by a non-zero whole number, and compute such quotients.
Interpret division of a whole number by a unit fraction, and computer such quotients.
Solve real-world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fraction.
