Answer 1

@jim_thompson5910

Answer 2

yes I agree. The distance is somewhere between 7 and 8, so probably halfway at 7.5

Answer 3

Although, now that I look at it more carefully. The 0 isn't over the left side. There's a bit of overhang.

Answer 4

ah so maybe 8.5?

Answer 5

yeah that could be a better possibility

Answer 6

To read a vernier scale, the rough reading is as @jim_thompson5910 said, take the reading against the "0" of the vernier (bottom) graduation. That reads approximately 8.5.
Now you move on the the vernier scale, and look for that graduation that is exactly against the upper scale. This gives the decimal (estimated portion).
We see that at 4, the graduation is slightly to the right, at 5 it is right on, and at 6, it is a bit to the left, so the estimated part is 5, or 8.5 is the reading, at @jim_thompson5910 gave as I typed.
