$sqrt30/15$

Rationalize $2/sqrt30$

Multiply by $sqrt30/sqrt30$ (which equals one).

$2/sqrt30 * sqrt30/sqrt30 =(2sqrt30)/sqrt900 =(2sqrt30)/30$

The fraction $2/30 = 1/15$ , so...

$(2sqrt30)/30=(1sqrt30)/15=sqrt30/15$

The square root of $30$ cannot be further simplified because it has no factors which are perfect squares.
