Understand a fraction π’/π£ with π’ > 1 as a sum of fractions 1/π£.
Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.
Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
Interpret the product (π’/π£) Γ π² as a parts of a partition of π² into π£ equal parts; equivalently, as the result of a sequence of operations π’ Γ π² Γ· π£.
Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number; and relating the principle of fraction equivalence π’/π£ = (π―Γπ’)/(π―Γπ£) to the effect of multiplying π’/π£ by 1.
Interpret division of a whole number by a unit fraction, and compute such quotients.
