There are four requirements that need to be satisfied:
A. Closure: For any two elements of the group, a and b, the operation a*b is also a member of the group.
B. Associativity: For any three members of the group, a*(b*c) = (a*b)*c
C. Identity: There exists an element in the group, called the identity and denoted by i, such that a*i = i*a for all a in the group. For real numbers with multiplication, this element is 1.
D. Inverse: For any member of the group, a, there exists a member of the group, b, such that a*b = b*a = 1 (the identity). b is called the inverse of a and denoted by a-1.

Let z be a complex number such that Imz 0 Prove that Im1z 0?
If the imaginary part of z is 0, then z is simply a real number and if you multiply by 1 which is the identity in multiplication of real numbers, you of course will still have a real number with imaginary part 0

How do people know fairies are real or not?
You cannot prove a negative. In order to prove that something is NOT real you first have to try to prove that it is real and fail. This has been known since the time of Aristotle. So the only proof that you can have of something not being real is a lack of proof of its existence. Not a convincing argument.
Is the set of negative integers closed under multiplication real numbers?
No, it is not.
