Adding and Subtracting Fractions where the denominators do share a common factor. The common factors on the top and bottom reduce to 1 (cancel out), The lowest common denominator isWrite each fraction over this common denominator, remember to multiply the top of the fractions too, Combine the fractions, as they have the same denominator, There are no terms which would cancel here, so this is the final answer, The lowest common denominator is (You could also use but this wouldn't be the lowest common denominator)Write each fraction over this common denominator, remember to multiply the top of the fractions too, There is nothing else that can be factorised on the numerator, so this is the final answer, Divide by, giving your answer as a simplified fraction, Division is the same as multiplying by the reciprocal (the fraction flipped), It can often help to factorise first, as there may be factors that cancel out, Multiply the numerators and denominators, and cancel any terms that are the same on the top and bottom. This can be achieved by first multiplying the top and bottom of the first fraction by 3, and then multiplying the top and bottom of the second fraction by 2.
