A television show lasted for 4$$ \frac{14}{15} hours $$. If $$\frac{1}{5}$$th of the total time was spent on advertisements, what was the actual duration of the television show?
Total duration of show =Â 4$$ \frac{14}{15} hours = \frac{74}{15} $$
Duration of advertisement =Â $$\frac{1}{5}th of the total time = \frac{1}{5} \times \frac{74}{15} hours =Â \frac {74}{75}$$
 Actual duration of the television show = $$ \frac {74}{15} - \frac{74}{75} = 3.94 hours$$
