Voltage Divider Parallel Circuit
You are making the problem more complex than it really is. There is shown that 10V will be across the top of R1 to the bottom of R6. The voltage across R6 will be the same as the voltage across the the combination of R6789. So compute R6789 and then use that value in the voltage divider equation with R1.

There is no need to look at the values R2345 at all in this problem analysis. They were either put there to confuse you or to be another part of the problem if it was a multipart question referring to the same picture.
