    we have \[\frac{7}{12m^3n},~~~ \frac{1}{4mn^2}\]

    one of them is m^3 and the other just m so to make it common need to multiply the other by m^2

    n is common too right so we need to multiply left one n top and bottom so we get n^2 for both fractions

    what about 12 and 4 the common multiple is 12 right (least common multiple)

    so we need to multiply the right fraction by 3 top and bottom

    so now we should have our common denominator ready
