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).
