Detailed Solution

We have 3 given numbers 0, 1, 2 on the scale.
So, a total 12 small spaces are added up to create the distance of 1 unit. Using a unitary system, we can tell that 1 small space is going to be the distance of  112 unit.
Now we need to find the fractional number of the point M.
This point is on the 2 steps to the right side of the mark 1.
Between the mark 1 and point M, there are 2 spaces which have a total distance of 2×112=16 unit.
So, the mark of M is the value of  1+16=76  unit.The mark M represents the fractional number  76.
