I found: $3/4sqrt(3)$

You can write your square root as:
$sqrt(27)/sqrt(16)=sqrt(3*9)/4=(sqrt(9)sqrt(3))/4=3/4sqrt(3)$

$(3sqrt(3))/4$

Use the quotient property of radicals to rewrite your expression as

$sqrt(27/16) = sqrt(27)/sqrt(16) = sqrt(27)/4$

Since $27$ is not a perfect square, you're going to have to see if you can write it as a product of a perfect square and another number

$27 = 9 * 3 = 3^2 * 3$

This means that your expression will be

$sqrt(3^2 * 3)/4 = (sqrt(3^2) * sqrt(3))/4 = color(green)((3 sqrt(3))/4)$
