12 is an integer and not a fraction. However, it can be expressed in rational form as 12/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
12 over 1 is the integer 12; it is not a mixed number. You could write it as 120/n where n is any non-zero integer but why would you do that? It would be a pointless exercise.
3 + 12*n hours where n is any integer, negative, zero or positive.
-12 is an integer and not a fraction. However, it can be expressed in rational form as -12/1. You can then calculate equivalent rational fractions if you multiply both, its numerator and denominator, by any non-zero integer.
12 is an integer.
