The multiplicative identity of a number leaves that number unchanged under multiplication. Thus the multiplicative identity of any number is 1.

It is 1, as it is for all complex numbers - which includes real numbers.
Additive identity: zero. Multiplicative identity: one.
Let m be a whole number, then the multiplicative inverse of m is a number n such that mn=1 since 1 is the multiplicative identity. There is only one choice for n, it is 1/m since m(1/m)=1
One.
Rational numbers and Real Numbers. The multiplicative inverses of integers are not integers.
