a rational number can be written as a fraction.

Any terminating or repeating decimal is also rational.

√5 is not rational. There is no fraction which is exactly equal to √5. The decimal value goes on forever and never repeats.

It is easy to prove that √5 is irrational, if you are interested. Just google proofs for √2 and follow the same logic you find there.
