N + 0.5N = 133.5
That is, 1.5 N = 133.5
so N = 133.5/1.5 and therefore, N = 89.

The number 2.
It's zero.
21/2 is itself a mixed number
No real number can be divided in half to become zero. When a number is divided in half, the result is half of that number, which is only zero if the original number is zero itself. Therefore, the only number that meets this condition is zero.
2 is the only prime even number, as prime numbers go into itself and 1. Even numbers tend to have, at the very least, 1 times itself and 2 times one-half of itself.
It is 3. 100% of any number is the number itself. (ie. 50% of any number is the half of the original number.)
The only such number is zero.
2 Yes but 2 divided by half of 2 (1) = 2 which isn't the lowest whole number. I don't think this question has an answer.
All you have to do is divide by two
