It is a number that can be expressed as a fraction but is NOT an integer. For example. 3 is an integer and it is rational since we can write 3/1, but 1/3 is not an integer and it is rational since we wrote it as a fraction or a ratio. Remember that a rational number is one that can be written as A/B where A and B are integers. Now if B is 1, which is certainly an integer, A/1 is rational but since A is an integer, A/1 is an integer.

-1 divided by 2 is a rational number because it can be expressed as a fraction in the form of -1/2
A rational number is one that can be written as a ratio - or fraction - between two integers. All integers can be written in the form (integer) / 1, and are therefore rational.

Any number, rational or irrational, can be divided by 1 and itself. A number divided by 1 does not change, and a number divided by itself is equal to 1. The definition of a rational number is a number which can be expressed as the ratio of two integers. So there is division involved, but not the kind you thought.
It is. A rational number is either an integer or a recurring decimal. An irrational number would be the square root of 2. There are also complex numbers that aren't rational or irrrational.
