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

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

This will give

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