Op Amp problem (urgent)

4.d. I=2V/8k ohm = 0.25 mA (As all V+ have no current going in)
VA1=1.5V
VB1=1V
VC1=0.5V

4.e. just use 100/101*each of VA1 VB1 VC1

Am I correct? Exam is next Monday so please help me asap!
The op amps are all being used as voltage folliwers (also called buffers)

The V output has to be the same as the V input on the non inverting input.

Probably you should revise your notes or look up op amp voltage follower on the internet to remind yourself.
