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

Adding Fractions b b 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

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

Multiplying Fractions b b 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

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
