Answer:
It is the closest to 0.
Step-by-step explanation:
You can solve this by giving them all the same denominator.
1/2 = 3/6
1 = 6/6
0 = 0/6
The difference of 1/6 from 1/2 is 2/6.
The difference of 1/6 from 6/6 is 5/6.
The difference of 1/6 from 0/6 is 1/6.
Since the last difference is the smallest, 1/6 is the closest to 0.
