Question

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

Answer 1

To find the expression that represents the number of dogs Russell has based on the total number of legs \( n \), we can use the fact that dogs typically have 4 legs.

Let:
- \( d \) be the number of dogs.
- The number of legs for dogs is given by \( 4d \).

If there are \( n \) legs in total, we can set up the equation:

\[
4d = n
\]

To express \( d \) in terms of \( n \), we can solve for \( d \):

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

Therefore, the expression that represents the number of dogs Russell has in his backyard, based on the number of legs \( n \), is:

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