9 + (3/x)/(x/4) + 1/12
= 9 + (3*4)/(x*x) + 1/12
= 9 + 12/x^2 + 1/12
= (108x^2 + 12 + x^2) / (12x^2)
= (109x^2 + 12) / (12x^2)

9 + 3 / x / x / 4 + 1 / 12
=9+3/x *4/x+1/12
=12/x+9+1/12
=12/x+109/12

You might need brackets to write the problem as it actually is, but taking what you've written literally:
3/x/x/4 = 3/x * 4/x = 12/x^2
so you have 9 + 12/x^2 + 1/12
108x^2/12x^2 +144/12x^2 +x^2/12x^2 =
(109x^2 + 144)/12x^2
