How do you know if its rational or irrational?

To show that the rational numbers are dense: An irrational number is a number that is NOT rational. It cannot be expressed as a fraction with integer values in the numerator and denominator. When an irrational number is expressed in decimal form, it goes on forever without repeating.

Is 1 3 a rational or irrational number?

A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.

Is 2.6 rational or irrational?

For example, 2.6 is rational because it can be expressed as a fraction 135. This is an example of a terminating decimal. Every terminating decimal has a finite number of digits, and all such numbers are rational. As another example, √2 = 1.414213…. is irrational because we can’t write that as a fraction of integers.
