sqrt30/15

Explanation:

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.
