Not whole numbers. Yes to real numbers and integers.
Any set of numbers that contains it. For example: {1,2,3,-0.002} {sqrt(1), pi2, 1/93, -0.002, -73}
It means that the boundaries of the set are not included in the set. For example, consider the set of numbers that are bigger than 1 and smaller than 2. The set is bounded by 1 and 2 but neither of these belong to the set.
Rational because it can be expressed as a fraction in the form of -50/1
The Rationals, the set {1, 3 , 5.86, sqrt(59), -2/3, pi2}, the reals numbers, numbers between 5 and 6, etc.
odd numbers, perfect square numbers

To any set that contains it! It belongs to {-1}, or {45, sqrt(2), -1, pi, -3/7}, or all whole numbers between -43 and 53, or square roots of 1, or negatives of counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
It belongs to any set that contains it: The set of numbers between 3 and 4, The set containing only the number 3.1414 repeating, The set containing 1, 3.1414 (r) , and sqrt(37) The set of rational numbers, The set of real numbers, etc
4 belongs to any set that contains it. So {1, pi, 4, -37.5689, sqrt(2)} is a possible answer.
To any set that contains it! It belongs to {0.25}, or {45, sqrt(2), pi, -3/7, 0.25}, or multiples of 0.05, or fractions between 0 and 1, or reciprocals, or rational numbers, or real numbers, or complex numbers, etc.
It is an irrational number.
The set of numbers that begin with the number 1 is Natural Numbers.
