I described what I did and attached a file. R2 and R3 are pretty much the same, and R4 + R5 is almost the same as R6. I am still confused why R3 + R6 doesn't equal to 1. Can you please give some steps of how to do this correctly?I have no idea how you arrived at your answers because we don't see your work.
But as a check for validity, current in R2 and R3 must be the same (except for rounding errors).
current in R4 + current in R5 = current in R6
current in R3 + current in R6 = current in R1
