Prove that \(\frac{2\sqrt{3}}{5}\) is an irrational.
 
Proof:
 
Assume \(\frac{2\sqrt{3}}{5}\) is
 
Therefore, \(\frac{2\sqrt{3}}{5}=\)
 
On simplification, \(\sqrt{3}=\)
 
Since \(p\) and \(q\) are integers, \(\frac{5p}{2q}\) is a
number. 
 
This implies that \(\sqrt{3}\) is a
number. 
 
But this contradicts the fact that \(\sqrt{3}\) is
.
 
Therefore, \(\frac{2\sqrt{3}}{5}\) is
.
