Here’s the classification of each number into the most specific set:
- 6.263: Rational Number
- 4.56666....: Rational Number
- −25: Integer
- 0: Whole Number
- 36−−√ (which equals 6): Natural Number
- 9/11: Rational Number
- 42−−√ (which is approximately 6.4807): Irrational Number
These classifications are based on the definitions of the sets:
- Natural Numbers: Positive integers (1, 2, 3, ...)
- Whole Numbers: Non-negative integers (0, 1, 2, ...)
- Integers: Whole numbers and their negatives (..., -3, -2, -1, 0, 1, 2, 3, ...)
- Rational Numbers: Numbers that can be expressed as a fraction of integers (like 1/2, -4, 0.75)
- Irrational Numbers: Numbers that cannot be expressed as a fraction of integers (like √2, π)
