expr =  (1.  t^3 + 2 t^5) / ( t^2 ( 3 + 4 t^2) )

3      5
1. t  + 2 t
-------------
2         2
t  (3 + 4 t )

(* The combination of Expand and Together do the trick *)
(* in your particular case *)
Together[Expand[expr  ] ]

3
2 (0.5 t + t )
--------------
2
3 + 4 t

(* To avoid the number two outside *)
ExpandNumerator[Together[Expand[expr  ] ] ]

3
1. t + 2 t
-----------
2
3 + 4 t

Hope this is of some help.
