The hierarchy of number sets within the real number system from largest to smallest is generally arranged as follows:
- Real Numbers (ℝ) - Includes all the rational and irrational numbers.
- Rational Numbers (ℚ) - Numbers that can be expressed as a fraction of two integers (e.g., 1/2, 3, -4).
- Integers (ℤ) - Whole numbers, including negative numbers, zero, and positive numbers (e.g., -3, 0, 2).
- Whole Numbers - Non-negative integers (0, 1, 2, 3, ...).
- Natural Numbers (ℕ) - Positive integers (1, 2, 3, ...).
- Whole Numbers - Non-negative integers (0, 1, 2, 3, ...).
- Integers (ℤ) - Whole numbers, including negative numbers, zero, and positive numbers (e.g., -3, 0, 2).
- Rational Numbers (ℚ) - Numbers that can be expressed as a fraction of two integers (e.g., 1/2, 3, -4).
In summary, the correct order from largest to smallest is:
Real Numbers > Rational Numbers > Integers > Whole Numbers > Natural Numbers.
Note: The hierarchy isn't strictly about size in value, but rather about the inclusiveness of each set within the overall structure of numbers.
