  • The method for subtracting fractions is the same as for adding fractions. You can only subtract fractions with the same denominator.

    To subtract fractions with different denominators you must:

    1. Find the lowest common denominator (LCD). 
    2. Rewrite each fraction into an equivalent form using the LCD.
    3. Subtract the fractions, keeping the LCD as the denominator.
    4. Simplify the final answer if needed.
    This method is discussed in detail in the following video.
