Is 16 a prefect number?
16 is not a perfect number as defined by Euchlid and Euler. 6 is a perfect number, by their definition, because it is the sum of all its proper positive divisors - all numbers that will divide into the number excluding itself - (1 + 2 + 3) = 6, and equal to half the sum of all its positive divisors, including itself (1 + 2 + 3 + 6)/2 = 6. 28 is the next number. There is still an unsolved mystery in number theory as to whether there can be an odd perfect number.
Is one half a rational number or a natural number?
Rational: yes. Natural: no.
Is 4 and a half natural number?
no
Is a happy number times another happy number always a happy number?
Well if you mean positive then yes a positive times a positive is always a positive! Those numbers always have their calculators half full :)
Is three and one half a natural number?
No. A natural number has no fractional part (or digits after a decimal point).
Why is 496 a perfect number?
Divisors of 496 are 1, 2, 4, 8, 16, 31, 62, 124 and 248 and the sum of all these divisors is 496 (1+2+4+8+16+31+62+124+248=496) so 496 is a perfect number.The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and 1 + 2 + 3 = 6. Equivalently, the number 6 is equal to half the sum of all its positive divisors: (1 + 2 + 3 + 6) / 2 = 6.

Why is 25 an abundant number?
25 is not an abundant number because the sum of its divisors is less than half of 25. The lowest odd abundant number is 945.
Is 8 and a half a Natural number?
No it is not a natural number its a decimal or fractional number

Rational: yes. Natural: no.
Is 4 and a half natural number?
no

What year was colt police positive number 241386made?
A Colt police positive special with that serial number was made in the latter half of 1921.
Is there a smallest positive rational number?
1/infinity? * * * * * Nice idea but unfortunately that is not a rational number, which is defined as the ration of two integers, x/y where y > 0. Since infinity is not an integer, the suggested ratio is not a rational number. The correct answer is that there is no such number. If any number laid claim to being the smallest positive rational, then half of that number would have a better claim. And then a half of THAT number would be a positive rational that was smaller still. And so on.
What is a positive number such that one half times one third of the number multiplied by one sixth is equal to the number itself?
The only such number is zero.
