Question

Jess watched a movie that was 1 and 3/4 hours long with her friends. After Watching 1/3 of the movie . How many hours of the movie did Jess still have left to watch

Answer 1

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}`
