Real numbers; also the rational numbers.
Sure! 15 belongs to several sets of numbers, including the natural numbers, whole numbers, integers, rational numbers, and real numbers. In each set, 15 is classified based on its properties and relationships with other numbers. These sets form a hierarchy, with each set containing the previous set as a subset.
It belongs to the set ofrational numbers,decimal fractions,improper fractions (in decimal form),real numbers,complex numbers,quaternions.
Negative integers, rationals and real 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.
