It is rational.
A rational number is one that can be expressed as one integer over another (p/q) where the bottom number q is not zero.
Particularly the bottom number q can be 1, that is p/1 are rational numbers.
But any number divided by 1 is the number itself, that is p/1 = p where p is any integer
0 is an integer, thus 0 is a rational number.

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 0.555555 both rational and irrational rational neither rational nor irrational irrational?
No number can be both rational and irrational. And, at the level that you must be for you to need to ask that question, a number must be either rational or irrational (ie not neither). 0.555555 is rational.
Is the square root of -57 rational or irrational?
Neither. It is an imaginary number.
Is 0.686868 irrational rational both or neither?
If it ends there, it is rational. If the "68" continues on and on, it is also rational.
Is 0.686868 rational irrational both rational and irrational or neither rational nor irrational?
Irrational* * * * *No.The number can be represented by a terminating decimal so it is rational.A number cannot be both rational and irrational. And unless you are into higher maths (and if you are, the distinction between rationals and irrationals will be child's play) there are none that are neither rational nor irrational. So, for your purposes, they must be one or the other but cannot be both.Even if it is an infinite decimal, with 6868 going on for ever, it is rational.
Is the square root of nine over zero rational or irrational?
Neither. It is not defined.
Is 0 a rational or irrational number?
Zero (0) is a rational number, because it is a whole 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 0.555555 both rational and irrational rational neither rational nor irrational irrational?
No number can be both rational and irrational. And, at the level that you must be for you to need to ask that question, a number must be either rational or irrational (ie not neither). 0.555555 is rational.
Is three an irrational number rational number both rational and irrational or neither rational or irrational?
Integers are rational. In the set of real numbers, every number is either rational or irrational; a number can't be both or neither.
Is the number below rational irrational both rational and irrational or neither rational nor irrational?
If it can't be expressed as a fraction then it is an irrational number
Is the product of a rational number and an irrational number rational or irrational?
Such a product is always irrational - unless the rational number happens to be zero.
Is the square root of 225 rational or irrational?
Neither, it is an imaginary number and imaginary numbers are neither rational nor irrational.
What is the result of an irrational number times an rational number?
Unless the rational number is zero, the answer is irrational.
Is the product of a rational and irrational number always irrational?
No, but the only exception is if the rational number is zero.
What does a rational number times an irrational number equal?
The product of 0 and an irrational is 0 (a rational), the product of a non-zero rational and any irrational is always irrational.
Why is the product of a non - zero rational number and an irrational number is irrational?
Let q be a non-zero rational and x be an irrational number.Suppose q*x = p where p is rational. Then x = p/q. Then, since the set of rational numbers is closed under division (by non-zero numbers), p/q is rational. But that means that x is rational, which contradicts x being irrational. Therefore the supposition that q*x is rational must be false ie the product of a non-zero rational and an irrational cannot be rational.
