Multiplying fractions as scaling - fractions, whole number fractions, and mixed numbers against a whole number. Students must decide if the product will be less than, greater than, or equal to the whole number and must justify their answer.

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―Γπ’)/(π―Γπ£) to the effect of multiplying π’/π£ by 1.
Comparing the size of a product to the size of one factor on the basis of the size of the other factor, without performing the indicated multiplication.
