It belongs to the rational numbers which is a subset of the real numbers. The reals, in turn, is a subset of complex numbers.
Yes.
The subset consisting of the one number, 7.5 : {7.5}
No. Natural numbers are a very small subset of real numbers.
-4.2 is a negative decimal number. It is also a directed number.

Rational (β) which is a subset of Real (β) which is a subset of Complex (β).
It belongs to any subset which contains it. For example,the interval (3, 4){pi}{1, pi, 3/7}{27, sqrt(7), pi}

No. There are several real numbers that are not rational (e.g. pi). However, every rational number is also a real number. In general, whole numbers/natural numbers is a subset of the integers (i.e. every whole number is an integer), the integers is a subset of the rationals, the rationals are a subset of the real numbers. I think the real numbers are a subset of the complex numbers, but I'm not 100% positive on that.
Yes.

I'm just telling you this ahead of time...but i'm not 100% sure with this answer..: fractions belong in the Rational Numbers
No. Natural numbers are a very small subset of real numbers.
