Have you attempted this question yourself? If so please put them up, it is easier for people/people are more inclined to provide you with assistance if your attempts are posted.

have you tried redrawing the circuit in it's simplest form? the series-parallel circuit can be redrawn to be a series circuit, then the math is easy after that.

you could begin furthest away from the voltage source and redraw the parallel portions to series and make your math simpler.

just a thought

Q3E) Draw the circuit showing clearly how she could adapt her meter
connection, using a device or circuit taught in the lectures, to measure the​
correct value of V
AB.

What were you taught in the lectures?

I don't get 1.274v for vAB

Does your book say that's correct?
