If you're talking about real numbers, then it is an irrational number. Any number that cannot be written as a fraction is irrational. You cannot write pi as a fraction (22/7 is just an estimate). So any thing multiplied with pi cannot be rational either.

What set of numbers does 30 belong to?
To any set that contains it! It belongs to {30}, or {45, sqrt(2), 30, pi, -3/7}, or all whole numbers between 23 and 53, or multiples of 5, or square roots of 900, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
How can a number belong to more than one set of numbers?
A set is just a way of describing numbers, and numbers can be described in more than one way. If set A is (for example) all positive prime numbers, and set B is all numbers between 0 and 10, then there are some numbers (2, 3, 5, and 7) that could belong to both sets.
What set of numbers does not include pi divided by pi?
Any set that does not contain the number 1. For example, even integers, multiples of 3, or 4, or 5, ... (0, 1) {1/2, 2/3, 3/4, 4/5, ...} {pi, pi2, pi3, ... }
What number set does seven belong to?
Natural (counting) numbers; integers; rational numbers; real numbers; complex numbers. And any other set that you choose to define, that happens to include the number 7 - for example, the set of odd numbers, the set of prime numbers, the set of the numbers {5, 7, 14, 48}, etc.
What set of numbers does -12 belong to?
Any set that contains -1.2, whether finite or infinite. For example, the set consisting of only -1.2 ie {-1.2}, the set consisting of -1.2 and 5 = {-1.2,5}, the set consisting of -1.2 and 3 and sqrt(17) = {-1.2,3,sqrt(17)}, and so on.
To which set of numbers does ( - 4/9 ) belong?
-5
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.
What set of numbers does 45 belong to?
To any set that contains it! It belongs to {45}, or {45, sqrt(2), pi, -3/7}, or all whole numbers between 43 and 53, or multiples of 5, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
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 set of numbers does 30 belong to?
To any set that contains it! It belongs to {30}, or {45, sqrt(2), 30, pi, -3/7}, or all whole numbers between 23 and 53, or multiples of 5, or square roots of 900, or composite numbers, or counting numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
Which set of numbers do -5 belong?
Integers. (This includes negative whole numbers.)
What set do these numbers below to -23 -14 -5 0 6 17 28?
Assuming that "below" is a typo for "belong", the answer is any set that contains them!For example,{-23, -14, -5, 0, 6, 17, 28},{-23, -14, -5, 0, pi, 6, 9, 12, 17, 28},Z, the set of integers,Q, the set of rational numbers,R, the set of real numbers,C, the set of complex numbers,the set of integers between -30 and +30,the set of rational numbers between -97/4 and 141/5,the set of square roots of all non-negative numbers less than 900.
Which group of sets does the number -15 belong to?
To any set that contains it! It belongs to {-15}, or {sqrt(2), -15, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or composite numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
What set of numbers does - 5 belong to?
The integers. Also: the rational numbers, the real numbers and (depending on your definition) the complex numbers.
How can a number belong to more than one set of numbers?
A set is just a way of describing numbers, and numbers can be described in more than one way. If set A is (for example) all positive prime numbers, and set B is all numbers between 0 and 10, then there are some numbers (2, 3, 5, and 7) that could belong to both sets.
What number set contains the number -5?
To any set that contains it! It belongs to {-5}, or {-5, sqrt(2), pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or negative integers, or rational numbers, or real numbers, or complex numbers, etc.
What set of numbers does 5.86 belong to?
The Rationals, the set {1, 3 , 5.86, sqrt(59), -2/3, pi2}, the reals numbers, numbers between 5 and 6, etc.
