Since Jess watched


\begin{gathered} (1)/(3)of1(3)/(4)\text{ of the movie, she still has to watch } \\ 1(3)/(4)\text{ - }(1)/(3)(1(3)/(4))\text{ of the movie } \end{gathered}

This will give


(7)/(4)\text{ - }(1)/(3)((7)/(4))
\begin{gathered} (7)/(4)\text{ - }(7)/(12)\text{ = }(7)/(6) \\ 1(1)/(6)\text{hours left } \\ So\text{ she still has } \\ 1(1)/(6)\text{hours left or }1(2)/(12)\text{hours left } \end{gathered}
