Zero is a rational number. It can be written as a ratio: 0/1, 0/2, etc.
From MathsIsFun, here is a formal definition (I copied and pasted, OK)
A rational number is a number that can be in the form p/q where p and q are integers and q is not equal to zero.
Besides, for the set of rational numbers to be closed for addition and subtraction, it is necessary for zero to be a rational number. Example: If you say that you can add any two rational numbers and get another rational number, then what happens if you add 1/2 and -1/2, you get zero, so zero would need to also be a rational number.
Yes because it can be expressed as a quotient of two integers. (i.e. 0/1 or 0/2 etc.)

A rational number
Which rational number that is equal to its negative?
Zero is the only scuh number.
Is 0 a rational number?
Zero is a rational number. Rational numbers are numbers that can be represented by the division of two integers. Zero is zero divided by anything besides zero, so zero is rational.
When do you use a negative rational number?
You use a negative rational number when an answer is below zero.
Is zero a rational number but not an integer?
Zero is a rational number and an integer.
What happens when a rational number is divided by an irrational number?
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
Is O a rational number?
A rational number can be expressed as a fraction or ratio of two integers. Zero is an integer. Therefore, zero is a rational number EXCEPT, that the denominator of a rational number cannot be zero. You can't divide by zero.

Which rational number is negative of it self?
The only such number is zero.
What is a product of any rational number and zero?
zero
Why the product of nonzero rational number and a rational number is an irrational?
Actually the product of a nonzero rational number and another rational number will always be rational.The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)
What is multiplication of a rational number by zero?
Zero times anything is zero.
