Realy Analysis?

I am pretty much lost, could anyone elaborate on the term “dense”? Here is my problem:

Prove the irrationals are dense in the real numbers.

Thanks.

Dense comes up in topology also. Basically you are asked to prove that the closure of the irrationals is the set of real numbers.

A set B is dense in C if the closure of B is C.
