Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.
A. Interpret division of a unit fraction by a non-zero whole number, and compute such quotients. For example, create a story context for (1/3) Ö 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3) Ö 4 = 1/12 because (1/12) × 4 = 1/3.
