3 Objective SWBAT review adding, subtracting, multiplying, and dividing fractions and mixed numbers. SWBAT review adding, subtracting, multiplying, and dividing fractions and mixed numbers.

4 Mixed Numbers to Improper Fraction 8 x 5 = = 41 Remember this??? Multiply Add

5 ADDITION & SUBTRACTIONREVIEW

6 Section 3-5 “Adding and Subtracting Fractions” Adding Fractions and Mixed Numbers with Common Denominators To ADD/SUBTRACT fractions with common denominators: 1) Rewrite as improper fractions (if necessary) 2) Add/subtract their numerators. 3) Simplify if necessary.

7 Fractions with Different Denominators To ADD or SUBTRACT fractions with different denominators follow these steps: 1). Rewrite as improper fractions (if necessary) 2). Rewrite the fractions using a common denominator. 3). Add or subtract the numerators. 5: 5, 10, 15, 20, 25, 30, 35, 40 7: 7, 14, 21, 28, 35, 42 What is the common denominator? Equivalent fractions

8 2.Common denominators 3. Subtract numerators 1.Improper fractions Mixed Number Practice

9 Simplify Subtract numerators “Opp-Opp” Commutative property Subtract numerators

10 MULTIPLICATIONREVIEW

11 Section 3-6, “Multiplying Fractions” Multiplying Fractions To multiply fractions: 1. Rewrite fractions as improper fractions (when necessary) 1. Rewrite fractions as improper fractions (when necessary) 2. Multiply the numerators and denominators. 2. Multiply the numerators and denominators. 3. Simplify if necessary. 3. Simplify if necessary.

12 Multiply Rewrite as improper fractions and assign negative to numerator. Divide (cancel) common factors Multiply 1 4 Simplify Mixed Number times Mixed Number

13 Word Problem Who ran farther Sally Jo or Sally Sue? Sally Jo ran 4 ½ times around a ½ mi. track. Sally Sue ran 3 ¼ times around a 5/6mi. track Sally Sue ran farther!!

14 Multiply Divide (cancel) common factors if possible MultiplySimplify Rewrite a whole number with a denominator of 1. Whole Number times Fraction Word Problem There are 36 students in your class. 2/3 of them went on the class trip. How many students went on the trip? 1 12

15 DIVISIONREVIEW

16 Section 3-7, “Dividing Fractions” Dividing Fractions To divide fractions: 1. Rewrite fractions as improper fractions (when necessary) 1. Rewrite fractions as improper fractions (when necessary) 2. Write the reciprocal of the second fraction. 2. Write the reciprocal of the second fraction. 3. Multiply the numerators and denominators. 3. Multiply the numerators and denominators. 4. Simplify if necessary. 4. Simplify if necessary.

17 RECIPROCAL – two nonzero numbers whose product is 1. RECIPROCAL = MULTIPLICATIVE INVERSE INVERSE

18 Divide Multiply by the RECIPROCAL Divide (cancel) common factors Multiply Assign negative sign to the numerator

19 A recipe that yields 2 loaves of bread requires 3½ cups of sugar. You have a bag of sugar that contains 14¼ cups. How many cups of sugar will be left in the bag if you make 8 loaves of bread? 8 loaves ÷ 2 loaves per batch = 4 batches 4 batches ∙ 3 ½ cups of sugar = 14 cups 14¼ cups – 14 cups for recipe = ¼ cup left over.

20 Benchmark Review Chapter 1 - Chapter 1 - Simplifying variable expressions Simplifying variable expressions a + b; when ‘a’ = -12 and ‘b’ = 7 a + b; when ‘a’ = -12 and ‘b’ = 7 Properties Properties Commutative = Commutative = Associative - Associative - Identity = 2 Identity = 2 Distributive - 2(n + 4) = 2n + 8 Distributive - 2(n + 4) = 2n + 8
