What determines how precise a measurement is
It is precise if it is repeatable.
Is as exact as possible
The precise measurement is 5.7 mm for the first value and 3.6 m for the second value.
2.5cm is the most precise measurement of the two measurements.
No. An answer is only as precise as the least precise measurement from which it was calculated.
What determines how precise a measurement is

You can make a very precise measurement with a poorly calibrated device.
No. Accurate relates to how close the actual measurement the instrument measures. Precise relates to how much detail the instrument gives when measuring. They are independent to each other: An measurement can be precise and accurate (eg the value of π is 3.141592654) An measurement can be precise and inaccurate (eg the value of π is 1.733677432) An measurement can be less precise and accurate (eg the value of π is 3.14) An measurement can be less precise and inaccurate (eg the value of π is 1.73).

An automatically measurement has a higher precision than a manually measurement.
Is as exact as possible
