  Amenability modulo an ideal of a Banach algebra have been defined and
studied. In this paper we introduce the concept of amenability modulo an ideal
of a Frechet algebra and investigate some known results about amenability
modulo an ideal of a Frechet algebra. Also we show that a Frechet algebra A is
amenable modulo an ideal if and only if A is isomorphic to a reduced limit of
amenable modulo an ideal of Banach algebras.
