Which Description Can Be Written as the Expression $\frac{n}{4} - 13$?

Understanding the Expression

The given expression is $\frac{n}{4} - 13$. This expression involves a fraction and a constant. To understand the expression, we need to break it down into its components. The fraction $\frac{n}{4}$ represents the quotient of a number $n$ and four. The constant $-13$ is a negative value that is being subtracted from the quotient.

Analyzing the Options

Now, let's analyze the given options to determine which one can be written as the expression $\frac{n}{4} - 13$.

Option A: Joel wants to find the quotient of a number and four, minus thirteen.

This option directly matches the expression $\frac{n}{4} - 13$. The quotient of a number and four is represented by the fraction $\frac{n}{4}$, and the minus thirteen is represented by the constant $-13$. Therefore, this option can be written as the expression $\frac{n}{4} - 13$.

Option B: Joel wants to find the product of thirteen and the quotient of a number.

This option does not match the expression $\frac{n}{4} - 13$. The product of thirteen and the quotient of a number would be represented by the expression $13 \times \frac{n}{4}$, which is not the same as the given expression.

Option C: Joel wants to find the quotient of a number and four, plus thirteen.

This option does not match the expression $\frac{n}{4} - 13$. The quotient of a number and four, plus thirteen would be represented by the expression $\frac{n}{4} + 13$, which is not the same as the given expression.

Conclusion

Based on the analysis of the options, the correct description that can be written as the expression $\frac{n}{4} - 13$ is:

• Option A: Joel wants to find the quotient of a number and four, minus thirteen.

This option directly matches the expression $\frac{n}{4} - 13$, and it provides a clear and concise description of the operation being performed.
