Multiplying Fractions

Author: Karla De La Torre

5.NF. 4 Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction. 
        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.)
