MULTIPLYING FRACTIONS

BASICS

• 2/4 x 4/8
• Numerator= top number
• Denominator= bottom number
• Numerators = 2 and 4
• Denominators= 4 and 8

WHAT IS A PROPER/IMPROPER FRACTION?

• Proper is where numerator has smaller value than denominator
• Ex: 2/4
• Improper is where numerator has larger value than denominator
• Ex: 9/5

WHAT IS A MIXED NUMBER?

• A mixed number is a whole number 'mixed' with a fraction
• Ex: 4 1/2 (four and one half)

CONVERT MIXED NUMBER

Untitled Slide

• Multiply the denominator with the whole number

Untitled Slide

• Step 2: add the product to the numerator
• Step 3: Sum becomes numerator, denominator is the same

CONVERT IMPROPER FRACTION

Untitled Slide

• Divide denominator into numerator

THE QUOTIENT BECOMES THE MIXED NUMBER

LEAST COMMON MULTIPLE

LCM

• Smallest #'s that the #'s are factored in

GREATEST COMMON FACTOR

GCF

• Highest # that divides into 2 or more #'s

SIMPLIFY A FRACTION

DIVIDE BOTH NUMERATOR AND DENOMINATOR BY A NUMBER THEY CAN BOTH BE DIVIDSD BY
