  1. Fractions By Brenda Langley

  2. Fractions • Can be whole numbers • Can be parts of a whole number • Can be added • Can be Subtracted • Can be multiplied • Can be Divided

  3. Fractions • Fractions consist of two numbers. The top number is called the . The bottom number is called the • numerator denominator numerator denominator.

  4. To add two fractions with the same denominator *add the numerators *place that sum over the common denominator 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 Adding Fractions

  5. 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 Subtracting Fractions

  6. 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 Multiplying Fractions

  7. 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 Dividing Fractions
