Component - 4.NF.4.a:
Understand a fraction a/b as a multiple of 1/b. For example, use a visual fraction model to represent 5/4 as the product 5 * (1/4), recording the conclusion by the equation 5/4 = 5 * (1/4).

Component - 4.NF.4.b:
Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. For example, use a visual fraction model to express 3 * (2/5) as 6 * (1/5), recognizing this product as 6/5. (In general, n * (a/b) = (n * a)/b.)

Component - 4.NF.4.c:
Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. For example, if each person at a party will eat 3/8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?
