Jermaine has just painted a large mural. it is 8 1/2 feet wide. the wall he wants to place it on is 11 3/4 feet wide. about how far from each side will he have to place the mural to ensure it is centered?

First turn 1/2 to 2/4 so you have a common denominator.
Next turn the mixed numbers into improper fractions:
11 3/4 --> 47/4 and 8 2/4 --> 34/4
Subtract:
47/4 - 34/4 = 13/4
Divide:
13/4 = 3.25
3.25/2 --> 1.625 or 1 5/8
Therefore, he will have to place it 1 5/8 feet from each side

Hope this helps!

9/12 is the answer because 3/4 times 3 each is 9/12
