2/5

Explanation:

We can leverage the radical property

sqrt(a/b)=sqrta/sqrtb

All this is saying is that the square root of the quotient is the same as the quotient of the square roots. We can now rewrite our expression as

color(blue)(sqrt12)/color(purple)(sqrt75)

This is equivalent to

color(blue)((sqrt4*sqrt3))/color(purple)((sqrt25*sqrt3))

Since we have a sqrt3 on the top and bottom, these cancel:

(sqrt4*cancel(sqrt3))/(sqrt25*cancel(sqrt3))

And we're left with

sqrt4/sqrt25

Which simplifies to

2/5

Hope this helps!
