    Make them improper, multiply the numerator by the inverse of the denominator.

    There ya go.

    Well let's see.

    22/7 / 4/7

    Wait well it seems like we can take a shortcut here and multiply the whole thing by 1 (ie 7/7)

    (22/7 / 4/7) * (7/7) = 22/4 = 11/2

    So yeah you almost got it right but if I had to take a stab at what you did wrong I'd say you multiplied the denominator by the inverse of the numerator instead of the numerator by the inverse of the denominator.
