Modeling Multiplication of a Fraction by a Mixed NumberMeasurement Modeling Multiplication of a Fraction by a Mixed Number
Multiplying Fractions & Whole NumbersWhen we multiply whole numbers we can model the multiplication to arrive at the answer. 3 Example: 4 x 3 4
Multiplying Fractions & Whole NumbersWe can also model the multiplication of two fractions. 2/3 Example: 3/4 x 2/3 = 6/12 =1/2 1 2 3 4 3/4 5 6
Multiplying Fractions & Whole NumbersUsing these ideas, we can now model fractions by mixed numbers. Example: 1/3 of 1½ 1/3 x 1½
Multiplying Fractions & Whole NumbersWe start with 1 ½ squares. 1 ½ 1/3 x 1½
Multiplying Fractions & Whole NumbersWe then divide the squares by 1/3 in the other direction. 1 ½ 1/3 1/3 x 1½
Multiplying Fractions & Whole NumbersHow many spaces are shaded by both the yellow and the pattern? This is the numerator in the answer. 1 ½ 1 2 3 1/3 1/3 x 1½
Multiplying Fractions & Whole NumbersHow many rectangles are there in ONE square? This is the denominator in the answer. 1 ½ 1 3 1/3 3 4 5 6 1/3 x 1½
Multiplying Fractions & Whole Numbers1/3 x 1½ = 3/6 = 1/2 1 ½ 1/3
Multiplying Fractions & Whole NumbersLet’s try this one: 2/3 of 1 1/4 =

REVIEW: Multiply Fractions with Models
Fractions Multiplying Fractions Is multiplication repeated addition? 1/2 ∙ 5 = 1/2 ∙ 5/1 = 1 ∙ 5 = 5/ 2 ∙ 1 = 2 So 1/2 ∙ 5/1 = 5/2 Now let’s make that.
