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.)
Zero (0) is a rational number, because it is a whole number and an integer.
A rational number
Zero is the only scuh 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.
Any positive rational number.
Zero is a rational number and an integer.
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero 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.
It is rational.
Zero (0) is a rational number.
Zero (0) is a rational number, because it is a whole number and an integer.
Zero is a rational number, not imaginary.
The answer is zero. It is rational, precise, and exact.
The only such number is zero.
zero
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)
Zero times anything is zero.
