Answer:
1/12
Explanation:
1/6 x 1/2 = 1/12
The answer would be 1/6 IF you took 1/6 of the full sheet of paper, but if you are taking 1/6th of half of the paper, then you are taking half the amount. Basically, you would need two 1/6 pieces of one half to be equivalent to one 1/6th piece on the full sheet.
I'm really sorry if my explanation sounds really confusing
