$\mathrm{ \frac{1}{ \sqrt{5} } }$

$\mathrm{multiply \: the \: numerator \: and \: denominator \: }$

$\mathrm{by \: \sqrt{5} }$

Hence,

$\frac{1}{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} }$

$= \frac{ \sqrt{5} }{ { (\sqrt{5}) }^{2} }$

$= \frac{ \sqrt{5} }{5}$

Hence, the rationalised form of 1/√5 is √5/5.
