Answer:
5/9=1/2
12/13=1
2/13=0
Step-by-step explanation:
These are just based on what I think and also
5/9=0.55... so closer to 0.5 which =1/2
12/13 is just really close to 13/13
2/13 is really close to 0/13 rather than 6.5/13, which is 1/2
Going out on a limb here and guessing that the function is

Please correct me if this isn't the case.
Recall that

which converges for

.
It follows that

Even integer: 2 x a, where a is a natural number without 0;
Odd integer : 2 x b + 1 , where b is a natural number;
So, 2 x a + 2 x b+ 1 = 2 x ( a + b ) + 1, which is an odd integer.
