To model the problem "Eight is the quotient of a number and five," we can denote the unknown number as \( n \). The quotient of \( n \) and \( 5 \) can be expressed as \( \frac{n}{5} \).
Thus, the equation based on the statement would be:
\[ 8 = \frac{n}{5} \]
This indicates that 8 is equal to the quotient of the unknown number \( n \) divided by 5.
Given the response options provided, we interpret this equation as:
The correct equation is: 8 = n / 5 a division problem.
