Answer:
![21\frac{3}{4}](https://tex.z-dn.net/?f=21%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
Step 1: Add the numbers.
20.25 can also be expressed as
, because
=
=
. So if we add
and 11, we would get ![31\frac{1}{4}](https://tex.z-dn.net/?f=31%5Cfrac%7B1%7D%7B4%7D)
Step 2: Solve
![31\frac{1}{4} -9\frac{1}{2}](https://tex.z-dn.net/?f=31%5Cfrac%7B1%7D%7B4%7D%20-9%5Cfrac%7B1%7D%7B2%7D)
- Subtract the whole numbers
![31-9=21](https://tex.z-dn.net/?f=31-9%3D21)
This means addition. Also, since our denominators are not the same value, we have to find the LCM (Least Common Denominator): What do 2 and 4 have in common that they can divide themselves by? 4. We know this because 2 divided by 4 is 2, and 4 divided by 4 is 1, so they can both divide themselves by 4.
![\frac{5}{4}-\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D-%5Cfrac%7B1%7D%7B2%7D)
LCM
![\frac{5}{4}-\frac{2}{4} =\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D-%5Cfrac%7B2%7D%7B4%7D%20%3D%5Cfrac%7B3%7D%7B4%7D)
Therefore, the simplified expression to this is

Divide the length of the wall by 2 to find the center of the wall:14/2 = 7 feet
The center of the painting is 2/2 = 1 foot.
The edge of the wall would be the center of the wall minus the center of the painting:
7 - 1 = 6 feet.
There should be 6 feet on each side of the painting.
