Explanation:

Step1: Read main - scale value

The main - scale reading is 1.125 inches. The value on the main scale to the left of the thimble is 1 inch, and the additional 0.125 inches comes from the half - inch and quarter - inch markings.

Step2: Read thimble value

The thimble has 12.5 divisions. Each division on the thimble represents 0.0001 inches. So the thimble reading is \(12.5\times0.0001 = 0.00125\) inches.

Step3: Calculate total reading

Add the main - scale reading and the thimble reading. \(1.125+0.00125 = 1.12625\) inches.

Answer:

1.12625
