  is called the . The bottom
  number is called the
  
• numerator denominator

numerator
denominator.
4
Adding Fractions

• To add fractions with different denominators
• find the Least Common Denominator (LCD) of
  the fractions
• rename the fractions to have the LCD
• add the numerators of the fractions
• simplify the Fraction

• To add two fractions with the same denominator
• add the numerators place that sum over
  the common denominator

5
Subtracting Fractions

• To subtract two fractions with the same
  denominator
• subtract the numerators
• place that difference over the common
  denominator.

• To Subtract Fractions with different
  denominators
• Find the Lowest Common Denominator (LCD)
  of the fractions
• Rename the fractions to have the LCD
• Subtract the numerators of the
  fractions The difference will be the numerator
  and the LCD will be the denominator of the
  answer.
• Simplify the Fraction

6
Multiplying Fractions

• To Multiply Fractions
• Multiply the numerators of the fractions
• Multiply the denominators of the fractions
• Place the product of the numerators over the
  product of the denominators
• Simplify the Fraction

7
Dividing Fractions

• To Divide Fractions
• Invert (i.e. turn over) the denominator fraction
  and multiply the fractions
• Multiply the numerators of the fractions
• Multiply the denominators of the fractions

• Place the product of the numerators over the
  product of the denominators
• Simplify the Fraction
