5.NOS.D.11: Apply and extend previous understandings of multiplication to multiply a whole number by a fraction (c/d × b). a. Estimate products by reasoning about benchmark numbers and assess reasonableness of answers (e.g., 3/4 × 2 will be less than 2 because I am creating a fractional part of 2). b. Multiply a whole number by a fraction (e.g., interpret c/d × b as c/d of b when c/d is greater than or less than 1).
