Answer:
B. 6 2/3
Explanation:
After subtracting the width of the picture from the width of the wall, we find the length of the space to be ...
14 5/6 - 1 1/2 = (14 -1) +(5/6 -3/6) = 13 2/6 . . . feet
Dividing that space in half gives ...
(13 2/6)/2 = (13/2) +(2/6)/2
= 6 1/2 +1/6 = 6 3/6 + 1/6
= 6 4/6 = 6 2/3 . . . . feet
The space on either side of the picture is 6 2/3 feet.
