Replace and ReplaceAll -- simple application

I am doing some manipulations in Mathematica and end up with
constructs such as "1." in the expressions. I want to convert these to
"1" and thereby eliminate them. However, these examples don't seem to
work. This is Mathematica 7 on OS X.

In[40]:=
Replace[1.(y1-1.yr),1.->1]
Out[40]= 1. (y1-1. yr) (* Nothing happens *)

In[39]:=
ReplaceAll[1.(y1-1.yr),1.->1]
Out[39]= y1-1. yr (* Only first one is replaced *)

Any help is appreciated. Thanks.
