How to derive anti-fundamental representation of SU(5)?

On page 605 of Srednicki's textbook "Quantum Field Theory", it is stated:

Under the [math] SU(3)\times SU(2)\times U(1) [\math] subgroup, the fundamental and anti-fundamental representations of SU(5) transform as

[math]
\begin{equation}
\5 \rightarrow (3, 1, -\frac{1}{3}) \oplus (1, 2, +\frac{1}{2}) .\tag{97.2}
\end{equation}
\begin{equation}
\overline{5} \rightarrow (\overline{3}, 1, +\frac{1}{3}) \oplus (1, 2, -\frac{1}{2}) .\tag{97.3}
\end{equation}
[\math]

How is eq. (97.3), the anti-fundamental representation of SU(5), derived?
