The resistance of them each is 100ohms and 383.1944444 ohms or 27590/72.

I tried the formula 1/R1+1/R2 but I am not getting the right answer. Can anyone point me in the right direction please? Also how do i calculate voltage at each node? I am not too familiar with that and I goggled around and did not find anything helpful. I am trying to find voltage through each node in this circuit . it is problem number 1d. Any help would be appreciated.
