Say if the number is a whole,integer,rational, or irrational.
For example: -3.5 is irrational.
But 2 is whole, integer, and rational.

The above is absolute rubbish.
-3.5 is rational (-7/2), not irrational.
Also, it mentions the subsets of real numbers, whereas the question is about what the real numbers are a subsets of - the supersets of real numbers.
Actually, the set of real numbers is probably the largest set of numbers that you will come across in Secondary School (age 16-ish). If you continue with mathematics beyond that you will come across complex numbers: real numbers are a subset of complex numbers. There are supersets of complex numbers as well but you will not come across them unless you study mathematics to a seriously high level.

The real number 1.24 is a rational number (124/100). It is also a mixed number (1 + 24/100ths).
Negative integers, rationals and real numbers
It belongs to any set that has -17 amongst its members.Given that this is schoolwork, the answer teacher probably wants is: the set of integers.It also belongs to the set of rational numbers, the set of negative integers, the set of real numbers, the set of complex numbers, the set {43.2, 98, -17, pi} and an infinite number of others.It belongs to the set of complex numbers in spite of having no 'imaginary' part. Real numbers are just special cases of complex number in which the imaginary part happens to be zero. Rational numbers are special cases of real numbers. Integers are special cases of rational numbers.
Rationals and the reals, themselves.
To any set that contains it! It belongs to {sqrt(30)}, or {45, sqrt(30), pi, -3/7}, or irrational numbers, or real numbers between -6 and 6, or all real numbers or complex numbers, etc.
Rational numbers and Real numbers
Real numbers; also the rational numbers.
-29 is an element of the real number system. That is to say, it belongs to the set of real numbers.
It is a rational and real number.
Negative rational numbers; Negative real numbers; Rational numbers; Real numbers. The number also belongs to the set of complex numbers, quaternions and supersets.
-5 to a set number is -5
Of the "standard sets" -10 belongs to: ℤ⁻ (the negative integers) ℤ (the integers) ℚ⁻ (the negative rational numbers) ℚ (the rational numbers) ℝ⁻ (the negative real numbers) ℝ (the real numbers) ℂ (the complex numbers) (as ℤ ⊂ ℚ ⊂ ℝ ⊂ ℂ). Other sets are possible, eg the even numbers.
Lots of numbers do. To begin, all real numbers do. Multiples of sqrt(-1), aka. imaginary numbers, do. The Complex Numbers are all numbers which are the sum of a real number and an imaginary number.
It belongs to the interval (25, 27.3), or [-20.9, 10*pi], and infinitely more such intervals.It also belongs to the set of rational numbers, real numbers, complex numbers and quaternions.
It belongs to the set ofrational numbers,decimal fractions,improper fractions (in decimal form),real numbers,complex numbers,quaternions.
The real number 1.24 is a rational number (124/100). It is also a mixed number (1 + 24/100ths).
Integers, odd integers, negative integers, odd negative integers, rational numbers, negative rational numbers, real numbers, negative real numbers, square roots of 1, etc.
