Would I perform this: \[\frac1{12}\left[\begin{matrix}2 & 1 \\ 4 & 4\end{matrix}\right]\]

yup :)

Alright, so the answer would be: \[\left[\begin{matrix}\frac16 & \frac1{12} \\ \frac13 & \frac13\end{matrix}\right]\]

Is there supposed to an aboslute value on the A? not sure...I thought that a and d switched places and that b and c negated...maybe I'm wrong?
