Question

Russell has many dogs in his backyard. Which expression below represents the number of dogs he has his backyard if there are n legs?

n + 4

4n

n/4

n - 4

Answer 1

To find the number of dogs Russell has in his backyard based on the total number of legs \( n \), we need to remember that each dog has 4 legs. Therefore, if \( d \) is the number of dogs, the total number of legs can be expressed as:

\[
n = 4d
\]

To solve for \( d \), we rearrange the equation:

\[
d = \frac{n}{4}
\]

Thus, the expression that represents the number of dogs Russell has in his backyard, given \( n \) legs, is

\[
\frac{n}{4}
\]

So, the correct answer is:

\(\text{n/4}\)
