1/2
Zero (0) is a rational number.
No, all integers are rational, whole numbers.
No, a rational number must be a whole number, for example 40 and 5643 and 948.
An irrational number cannot be written as a fraction or to an exact decimal such as the symbol for pi or the square root of two. A rational number can be written in the form of a fraction or a decimal to an exact value.
Yes, negative numbers can most certainly be rational. A rational number is simply a number which can be expressed as a fraction. An example of a negative rational number is: -1/2

No, but you can add an irrational number and a rational number to give an irrational.For example, 1 + pi is irrational.
The square root of any positive square number is always rational as for example the square root of 36 is 6 which is a rational number.
Zero (0) is a rational number.
No, all integers are rational, whole numbers.
All natural numbers are rational numbers.
That is one example of rational numbers.
One example is 13/17.
Every number that you can write with digits, and a decimal point or fraction bar if you need it, is a rational number. Very few of them are integers. Examples: 1/2 0.792461828459046 343/1928
No, a rational number must be a whole number, for example 40 and 5643 and 948.
All integers and fractions are rational numbers whereas irrational numbers can't be expressed as fractions as for example the square root of 2 can't be expressed as a fraction because it is a non-terminating decimal number.
An irrational number cannot be written as a fraction or to an exact decimal such as the symbol for pi or the square root of two. A rational number can be written in the form of a fraction or a decimal to an exact value.
