Yes
All integers are whole numbers that can be odd or even
They are integers.
In standard mathematics, there is no number that is both even and odd. Even numbers are defined as integers divisible by 2, while odd numbers are those that are not divisible by 2. Hence, a number cannot satisfy both conditions simultaneously.
"Odd numbers" and "even numbers" are defined for integers, not for decimals.
The density property does not hold for odd numbers in the same way it does for the set of all integers or real numbers. While there are infinitely many odd numbers, they are not densely packed within the integers; there are gaps between them (specifically, every even integer separates two odd integers). Thus, between any two odd numbers, there are even integers, indicating that odd numbers do not form a dense subset of the integers.
No. Even numbers, and odd numbers are subsets of the integers. Since 0.4 is not an integer, it is neither even nor odd.
Only integers (the whole numbers, including zero and negative whole numbers) are odd or even. Other numbers (like irrational numbers, fractions that don't simplify to integers, imaginary numbers, and so on) are neither odd nor even.
The number 6.3 is neither odd nor even because it is a decimal. Odd and even numbers are classifications for integers, which are whole numbers without fractions or decimals. In the case of 6.3, it is a rational number that falls between the integers 6 and 7 on the number line.
Neither. The property of odd or even applies only to integers (whole numbers).
The terms "odd" and "even" apply to integers (whole numbers), not to decimals or fractions.
No, it is not. The concept of even and odd numbers is applicable only for integers.
Odd integers are whole numbers that are not evenly divisible by 2. If you count, starting at 1, you will have alternating odd and even numbers. 1 is odd, 2 is even, 3 is odd, 4 is even, 5 is odd, 6 is even, 7 is odd, and so forth to infinity. Negative numbers have the same property (minus one is also odd, etc.) and zero is also an even number.
