No, but you can add an irrational number and a rational number to give an irrational.For example, 1 + pi is irrational.
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 a whole number,Like Pi for example
No, they are not. An irrational number subtracted from itself will give 0, which is rational.
The number 2468 is a rational number. A rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero. In this case, 2468 can be expressed as the ratio 2468/1, which makes it a rational number.

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.
No, a rational number must be a whole number, for example 40 and 5643 and 948.
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
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.
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
