Yes. 1 and a half is equivalent to 1.5. Since the decimal terminates, the answer is rational. If a number has a non-terminating decimal, such as pi (3.14159... etc), it is irrational. The most common Irrational Numbers are pi, phi, and square roots of all numbers not perfect squares (1,4,9,16,25,36,49 etc).

The number 1/14 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are both integers. In this case, 1/14 can be written as a fraction with 1 as the numerator and 14 as the denominator, making it a rational number.
Is every rational number a natural number?
No. 1/2 is a rational number but it is not a natural number.
