Answer:
C. 81÷3
Step-by-step explanation:
We want to write a numerical expression for the phrase: "the quotient of 81 and 3"
Quotient indicates division, so we must divide 81 by 3.
81÷3
This can be further simplified, but the questions asks for a numerical expression. This is defined as an expression with numbers and at least one operation. So, B is correct, because 81 divided by 3 is 27, but it is not a numerical expression.
Therefore, the best answer choice is C. 81÷3
