Explanation:

Step1: Read main - scale value

The main - scale value is 0.5 mm (since the half - millimeter mark is visible).

Step2: Read thimble - scale value

The thimble - scale value is 13.0 × 0.01 mm = 0.130 mm (as the 13th division on the thimble is aligned with the main - scale axis).

Step3: Calculate total reading

The total reading is the sum of the main - scale and thimble - scale values, 0.5 mm+0.130 mm = 0.630 mm.

Answer:

0.630
