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 computer quotients.
- Interpret division of a whole number by a unit fraction, and compute such quotients.
- Solve real-world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem.
