The fraction will not repeat if we can make a reduced fraction with only some power of "2" in the denominator

 

So

 

1/12   =  repeats

2/12 = 1/6  =  repeats

3/12 = 1/4  = 1/2^2   = terminates

4/12 = 1/3  = repeats

5/12 = repeats

6/12 = 1/2  = terminates

7/12 = repeats

8/12 = 2/3  = repeats

9/12 = 3/4 = 3/2^2 = terminates

10/12 = 5/6  = repeats

11/12 = repeats
