$\frac{2}{5}$
$(-\frac{6}{13})(-\frac{26}{30})$ $\longrightarrow$ multiply numerators and denominators =$(-\frac{6\times26}{13\times30})$ $\longrightarrow$ factor =$(-\frac{=\big/\!\!\!6\times2\times\big/\!\!\!\!13}{\big/\!\!\!\!13\ \times\big/\!\!\!6\times5})$ $\longrightarrow$ eliminate common factors =$\frac{2}{5}$
