Does every point on the real number line correspond to a rational number?
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.
To which set of numbers does the number -12 belong?
It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.
What subset of real numbers does fourteen belong?
To any set that contains it! It belongs to {14}, or {14, sqrt(2), pi, -3/7}, or all whole numbers between 3 and 53, or multiples of 7, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, etc.
Is a real number always sometimes or never a rational number?
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
What real number is nonterminating and a nonrepeating decimal?
The only real number that is non-terminating and non-repeating is Pi (pie)
What is the subset of pi?
pi is a single number , not a set. Since it is not a set, it cannot have a subset.
What group of real numbers does Pi belong to?
Pi is an Irrational number, which is one of the two subcategories of real numbers.
Is pi a complex number?
The set of real numbers are a subset of the set of complex numbers: imagine the complex plane with real numbers existing on the horizontal number line, and pure imaginary existing on the vertical axis. The entire plane (which includes both axes) is the set of complex numbers. So any real number (such as pi) will also be a complex number. But many people think of complex numbers as something that is "not a real number".

What subset of the real number system does -5 belong in?
To any set that contains it! It belongs to {-5}, or {45, sqrt(2), -5, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or integers, or rational numbers, or real numbers, etc.
Is pi a real number?
Pi is a real number
Which subsets of real number does 17 belong in?
Any subset which will have it! It is in {17}or {-3, pi, 17, sqrt(37/6)}or {45, bananas, France, cold}or all whole numbers between -43 and 53, or multiples of 17, or prime numbers, or counting numbers, or integers, or rational numbers, or real numbers.
What group of numbers does pi belong to?
Pi is both an irrational number and a transcendental number.
Ratio of circumference of a circle to its diameter?
The ratio is pi, a transcendental number, which is a subset of irrational numbers. pi is approximately equal to 3.14159
What is the real pi number?
3.141592653589793 is pi.
What are the different sets of real number?
There are an uncountably infinite number (a Continuum) of different subsets.The main ones are:Natural numbers, NIntegers, ZRational numbers, QIrrational numbers.However, {2.5, -9, pi} is also a subset.
