Keys to Subtracting Fractions
• If the denominators in the fractions are not alike, find the lowest common
denominator.
• Regroup if a minuend (the number you subtract from) is a whole number or the
fraction in a minuend is smaller than the fraction in a subtrahend (the number being
subtracted).
• Subtract the fractions first and then subtract the whole numbers.
Directions: Subtract the mixed numbers. Remember, reduce to the lowest term.
