    common denominator of 1/a + 1/b is ab

    however simplifying the complex fraction gives: (b-a) / (b + a)

    Step-by-step explanation:

    common denominator of 1/a + 1/b

    should be the product of the denominators

    a*b

    so 1/a + 1/b = (b + a) / ab

    ao

    (1/a - 1/b) divided by (1/a + 1/b) = (b - a) / (ab) divided by (b+a) / ab
