Observation
1
3/8″
The numeral strokes are those of the whole inches, between two of them, there is a slightly shorter stroke, which is half 1/2″, whose half is 1/4″; Its half is the eighth of of an inch, 3/8″.

1″

13/16″
The object is 1/16″ (see, the inch was divided into 32 parts, so each one is  1/32″.)  2 x 1/32″ = 2/32″, simplifying, = 1/16″) greater than 3/4″. So,  3/4″ = 6/8″ = 12/16″. 12/16″ + 1/16″ = 13/16.
4
13/32″
Note that the number next to where the zero should be indicates the smallest division of this part of the scale and a 32th of an inch. Count each space between the marks to the left of the lined one and you will see that they are 13 (13/32). Note that the trait on the left is 3/8 (exercise 1) remember that 3/8 = 6/16 = 12/32 which adding 1/32 results in 13/32 “

1.1/2″
7
1/4″
The object was positioned at the 1/4 inch mark and went up to the 1/2 (2/4) inch mark.
8
9/32″
See that the object was positioned 1/32″ left of the 1/4″ mark and went until the 1/2″ mark, (1/4 = 8/32) 8/32 + 1/32 = 9/32″

1.7/8″
