Answer:
[tex]7/\frac {1}{2}=7\times 2[/tex]
Step-by-step explanation:
To find the number of benches along the walkway, we need to simply divide the total distance of the walkway by the spacing. In this case, the walkway distance is 7 miles and the spacing of benches is 1/2 miles. Therefore, the expression for the number of benches along the walkway will be given by [tex]7/\frac {1}{2}=7\times 2[/tex] so both of these expressions can be used.
