Thank you so much.
But what are these values written in the marking scheme? i dont really get those.From where did they get 28/29.

And when finding the value on the stage micrometer,why did you take it as 10 units,not 3mm?
Because 20 is at 0 and 30 at 9. Therefore 30-20=10 corresponds to 9.

And I myself don't understand the table in the mark scheme, heh. I only checked the final answer and it matched the one I got, so I guess the method I used is correct.

No problem.
If you look at the picture again, there are 10 divisions between 2 and 3. That means between the 3 and 2, there's 10 units (because you have to count all the lines).
