Answer
$\color{blue}{\dfrac{19}{6k}}$
Work Step by Step
The expressions are not similar since they have different denominators.
Make the expressions similar using their LCD which is $2(3)(k) = 6k$ to obtain:
$=\dfrac{3\color{red}{(3)}}{2k\color{red}{(3)}}+\dfrac{5\color{red}{(2)}}{3k\color{red}{(2)}}
\\=\dfrac{9}{6k}+\dfrac{10}{6k}
\\=\dfrac{9+10}{6k}
\\=\color{blue}{\dfrac{19}{6k}}$
