Given :
Hu is installing a new window in his bedroom wall. He wants to center it horizontally.
The window is 40 1/2= 81/2 inches long, and the wall is 105 1/4= 421/4 inches long.
To Find :
How far from each edge of the wall should Hu install the window.
Solution :
Remaining size,
[tex]R = \dfrac{421}{4}-\dfrac{81}{2}\\\\R = \dfrac{259}{4}\ inches[/tex]
So, distance of the window form eah edge is [tex]\dfrac{R}{2}=\dfrac{259}{8}\ inches[/tex].
Hence, this is the required solution.
