  The aim of this paper is to obtain mixed weak-type inequalities for
multilinear fractional operators, extending results by F. Berra, M. Carena and
G. Pradolini \cite{BCP}. We prove that, under certain conditions on the
weights, there exists a constant $C$ such that $$\Bigg\| \frac{\mathcal
G_{\alpha}(\vec f \,)}{v}\Bigg\|_{L^{q, \infty}(\nu v^q)} \leq C \
\prod_{i=1}^m{\|f_i\|_{L^1(u_i)}},$$ where $\mathcal G_{\alpha}(\vec f \,)$ is
the multilinear maximal function $\mathcal M_{\alpha}(\vec f\,)$ that was
introduced by K. Moen in \cite{M} or the multilineal fractional integral
$\mathcal I_{\alpha}(\vec f \,)$. As an application a vector-valued weighted
mixed inequality for $\mathcal I_{\alpha}(\vec f \,)$ will be provided as well.
