zero
only one whole number is not a natural number and it is 0
One is.
The only non-natural whole number is 0.
name the only natural number that is neither prime nor composite? Answer is ONE
Depending on your definition of a natural number, 0 may or may not be a natural number. If you don't think 0 is a natural number, then it will be the only non-natural number that is whole.
0 is the only number which is in the set of whole number but not in the natural number
There is no such number.
All natural numbers (counting numbers) greater than one are either prime or composite. If divisible by only one and the number itself, it is prime; if divisible by other natural numbers, then is composite. One is the only natural number that is neither prime nor composite.
No, there are none.
No - the ONLY natural number which has a reciprocal which is also a natural number is "1". All the other reciprocals of natural numbers will be fractions that are less than 1.
A natural number.
Zero, by the traditional definition of natural numbers.
