Grade:	5th Grade
Standard:	CC.2.1.5.C.2
Description:	Apply and extend previous understandings of multiplication and division to multiply and divide fractions.
Standard:	M05.A-F.2.1.1
Description:	Solve word problems involving division of whole numbers leading to answers in the form of fractions (including mixed numbers).
Standard:	Math.5.NF.2 or 5.NF.A.2
Description:	Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < 1/2.
Standard:	M05.A-F.2.1.4
Description:	Divide unit fractions by whole numbers and whole numbers by unit fractions.
Standard:	Math.5.NF.6 or 5.NF.B.6
Description:	Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
Standard:	Math.5.NF.7c or 5.NF.B.7.C
Description:	Solve real world problems involving division of unit fractions by non-zero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3-cup servings are in 2 cups of raisins?

The four operations are addition, subtraction, multiplication, and division.

Representing and solving word problems involves choosing the correct operation(s).

$\frac{5}{8}$ - $\frac{1}{4}$	=	$\frac{5}{8}$ - $\frac{2}{8}$
	=	$\frac{3}{8}$

So,

\frac{3}{8}

more of the items at the bake sale are cookies than cupcakes.

To find how long Cheryl walked her dog, multiply

2 \frac{1}{3}

\frac{1}{4}

of an hour.

$2 \frac{1}{3}$ × $\frac{1}{4}$ hour	=	$\frac{7}{3}$ × $\frac{1}{4}$ hour
	=	$\frac{7}{12}$ hour

So, Cheryl walked her dog for

\frac{7}{12}

of an hour.
