5.NF.4.a: Interpret the product (a/b) * q as a parts of a partition of q into b equal parts; equivalently, as the result of a sequence of
operations a * q / b. For example, use a visual fraction model to
show (2/3) * 4 = 8/3, and create a story context for this equation. Do
the same with (2/3) * (4/5) = 8/15. (In general, (a/b) * (c/d) = ac/bd.)
