Final answer:
The expression representing the quotient of 16 and z minus 12 is (16/z) - 12.
Step-by-step explanation:
The question asks for the expression that represents the quotient of 16 and z minus 12. In mathematical terms, the quotient is the result of division, so the expression would be (16/z) - 12. This expression first divides 16 by z, and then subtracts 12 from the result.
