Answer:
(1, 8, 6) or (2, 12, 6) or (3, 24, 6)
Step-by-step explanation:
The last number must be 6:
1/2 = 6/12
The other two numbers cannot be 6, but can have several values:
1/2 = 1/8 +3/8 = 6/12
1/2 = 2/8 +3/12 = 6/12
1/2 = 3/8 +3/24 = 6/12
__
There are a variety of negative solutions as well. For example, ...
1/2 = -8/8 +3/2 = 6/12
