It is real and irrational.

phi = [1+sqrt(5)]/2 sqrt(5) is irrational and so phi is irrational.

No. 5 is not an irrational number. 5 is an integer (whole number) and all integers are rational - that is, they can be expressed as a ratio. In this case, 5/1.

Yes. 1/5 = 0.2, which is rational*. *A irrational number is one that cannot be expressed by a quotient, or fraction, of integers;for e.g., Pi = 3.141592..., infinitely, without ever repeating a finite sequence, is a real but irrational number.

82 is not an irrational number because it can be expressed as the quotient of two integers: 82÷ 1.
