It is a rational and real number.
10 belongs to the natural integer numbers
It belongs to the set of prime numbers
It belongs to the set ofrational numbers,decimal fractions,improper fractions (in decimal form),real numbers,complex numbers,quaternions.
Real numbers; also the rational numbers.
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.
10 belongs to the natural integer numbers
173 belongs to the set of positive natural numbers and it also belongs to the set of prime numbers.
The mean of a single number, such as 151, is the number itself, since the mean is calculated by dividing the sum of a set of numbers by the count of those numbers. Therefore, the mean of 151 is 151.
The number -4 belongs to the set of all integers. It also belongs to the rationals, reals, complex numbers.
It belongs to the set of prime numbers
It belongs to the set ofrational numbers,decimal fractions,improper fractions (in decimal form),real numbers,complex numbers,quaternions.
Rational numbers and Real numbers
30 belongs to the set of natural numbers
Real numbers; also the rational numbers.
10 belongs to the set "natural numbers", but it can also belong to whole numbers, and rational numbers
Any number that can be written as a fraction belongs to the set of rational numbers.
Because that is how the set of integers and the set of rational numbers are defined.
