- 4.NF.B.4aUnderstand 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 Ã (1/4), recording the conclusion by the equation 5/4 = 5 Ã (1/4).
- 4.NF.B.4bUnderstand 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 Ã (2/5) as 6 Ã (1/5), recognizing this product as 6/5. (In general, n Ã (a/b) = (n Ã a)/b.)
- 4.NF.B.4cSolve 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?

4.NF.B.4a

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 Ã (1/4), recording the conclusion by the equation 5/4 = 5 Ã (1/4).

4.NF.B.4b

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 Ã (2/5) as 6 Ã (1/5), recognizing this product as 6/5. (In general, n Ã (a/b) = (n Ã a)/b.)

4.NF.B.4c

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?
