Adding and Subtracting (with different denominators)

For fractions with different denominators, you must find EQUIVALENT fractions with the SAME denominator before you can add or subtract.

Notes CONTINUED:• Once you find the LCD (lowest common denominator), you must find the adjust

the numerators.• Then line the fractions up vertically (first one on top of the second one).• Finally, add or subtract the numerators, and keep the denominator the same.• Be sure to always SIMPLIFY an answer that is a fraction. If improper, turn it

into a mixed number.
