All mathematical operations are reversible and if you were correct then doubling zero would give you that number and the only number that fits both bills would be zero itself. So zero halved is zero and zero doubled is also zero.
yes, it is possible to divide zero by a number. It is not possible to divide a number by zero though, which is undefined.

No, it is not possible to divide 15 by a mixed number and get a quotient that is greater than 15.
No.
It is the number itself.
Yes, you divide the number of expected outcomes by the number of possible outcomes in order to determine probability.
Divide the number correct by the total possible.
