Hi is a new window in his bedroom wall he wants to center it horizontally the window is 40 1/2 inches long and the wall is 105 1/4 inches long how far from each edge of the wall should hi install the window

Answer 1

Take half of the difference between 105 1/4 inches and 40 1/2 inches:

(1/2)(104 5/4 - 40 2/4) inches = (1/2)(64 3/4 inches) = 32 3/8 inches.

Position the window 32 3/8 inches from each the left and right walls.
