No, a number is not always greater than its opposite. For any positive number, it is indeed greater than its opposite (negative counterpart), but for zero, the opposite is also zero, making them equal. For negative numbers, the opposite is a positive number, which is greater than the negative number. Thus, the relationship depends on the sign of the number.
no
It is not clear what you mean by "oppisites" or even opposite. Often a number is the opposite of its opposite. So if the first is greater than the second, the second, which is the opposite of the first, is smaller than the first.

No.The mixed number 21/2, for example, is greater than the whole number 2, but smaller than the whole number 3.In fact, given any mixed number (which does have a fractional part), it is always possible to find a pair of consecutive whole numbers such that the mixed number is between them.
Yes, a prime number is always greater than 1.
