The number of half-hour sittings needed to watch all the shows by Devon is 11
<u>Solution:</u>
Given, Devon records 4 hours of reality shows on her DVR
she records comedy shows for 3/8 of that amount of time.
![\rightarrow \frac{3}{8} \text { of } 4 \text { hours } \rightarrow \frac{3}{8} \times 4 \rightarrow \frac{3}{2} \text { hours }](https://tex.z-dn.net/?f=%5Crightarrow%20%5Cfrac%7B3%7D%7B8%7D%20%5Ctext%20%7B%20of%20%7D%204%20%5Ctext%20%7B%20hours%20%7D%20%5Crightarrow%20%5Cfrac%7B3%7D%7B8%7D%20%5Ctimes%204%20%5Crightarrow%20%5Cfrac%7B3%7D%7B2%7D%20%5Ctext%20%7B%20hours%20%7D)
Devon watches all the reality and comedy shows in half-hour sittings.
We have to find the number of half-hour sittings needed to watch all the shows
Now, number of half hour sittings is given as
![=\frac{\text { total time of videos }}{\text { time for hlaf hour sitting }}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%20%7B%20total%20time%20of%20videos%20%7D%7D%7B%5Ctext%20%7B%20time%20for%20hlaf%20hour%20sitting%20%7D%7D)
![\begin{array}{l}{=\frac{4 \text { hours for reality shows }+\frac{3}{2} \text { hours for comedy shows }}{\frac{1}{2} \text { hours for each sitting }}} \\\\ {=\frac{4+\frac{3}{2}}{\frac{1}{2}}=\frac{\frac{8+3}{2}}{\frac{1}{2}}=\frac{\frac{11}{2}}{\frac{1}{2}}=\frac{11}{2} \times \frac{2}{1}=11}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%3D%5Cfrac%7B4%20%5Ctext%20%7B%20hours%20for%20reality%20shows%20%7D%2B%5Cfrac%7B3%7D%7B2%7D%20%5Ctext%20%7B%20hours%20for%20comedy%20shows%20%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%20%5Ctext%20%7B%20hours%20for%20each%20sitting%20%7D%7D%7D%20%5C%5C%5C%5C%20%7B%3D%5Cfrac%7B4%2B%5Cfrac%7B3%7D%7B2%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B%5Cfrac%7B8%2B3%7D%7B2%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B%5Cfrac%7B11%7D%7B2%7D%7D%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cfrac%7B11%7D%7B2%7D%20%5Ctimes%20%5Cfrac%7B2%7D%7B1%7D%3D11%7D%5Cend%7Barray%7D)
