Make it easy on your self and drop the fractions and use even sizes strips with your 1/2" seam allowances. From your original post it sounds like your blocks may be 10" finished but can't really tell with the limited information.
Yes the finished block size is 10" for the three rows and I only use 1/4" seams.
