To any set that contains it!
It belongs to {-2.2},
or {45, sqrt(2), pi, -2.2, -3/7},
or all whole numbers between -43 and 53,
or multiples of 1.1,
or rational numbers,
or real numbers,
or negative rational numbers,
etc.
To any set that contains it! It belongs to {-22}, or {-22, sqrt(2), pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 11, or composite numbers, or integers, or rational numbers, or real numbers, etc.
It belongs to any set which has it as a member.The standard sets that include it are:Negative integer numbers (ℤ⁻)Integer numbers (ℤ)Rational numbers (ℚ)Real numbers (ℝ)Complex numbers (ℂ)Note: ℤ⁻ ⊂ ℤ ⊂ ℚ ⊂ ℝ ⊂ ℂ
22
Real numbers; rational numbers; integers; and of course you can make up lots of other sets to which it belongs.
A real number is just an ordinary number. The set of real numbers include all numbers between negative and positive infinity. Real numbers are ordered, and thus do not include imaginary numbers. A subset of real numbers refers to a group, or subsection, of real numbers. For instance, the numbers between 5 and 22 are a subset of real numbers. Another example of a subset is all even numbers, or all odd numbers.
Rational numbers.
Integers, Rational numbers, Real numbers and Complex numbers.
There are no prime numbers between 1 and 22.
yes example pi which is ratio of circumference of a circle by diameter. That is a real number which is APPROXIMATED as 22/7 but is not a rational number. Another example square root of 5,6,7. These are all real numbers but cannot be expressed as a rational number (p/q form)
22 because the rest are all prime numbers
They are 2 and 11
For natural numbers, 5 times. For all real numbers, infinitely many times.
