See explanation

Step-by-step explanation:

There are different kinds of analytical balances that read the mass of objects weighed in them to one, two, three or four decimal places as the case may be.

Most common analytical balances read the mass of objects to two or three decimal places hence the last 1 after the decimal point are likely to be approximated.

Hence, the scale may read 16.12 as the case may be.
