Answer: 43 1/12 (D)
Explanation:
As you may know, Sami cut 6 3/4 inches off and then we also know that the left over one are 36 1/3. If you put 6 3/4 together with 36 1/3, you get the whole picture of the paper. So in these case you will need to add those two together. Since they are both mixed numbers, turn them into improper fraction.
36 1/3 -> 109/3
6 3/4 -> 27/4
Since they do not has the same denominator, you need to find their common denominator, which is 12.
So 109/3 -> 436/12
27/4 -> 81/12
Add them together and turn them into mixed numbers again and you got 43 1/12 which is the last choice
Hope it helped! :)
