We have 6.75 yards, so first we will convert it into feet, applying a rule of three we have:
[tex]\begin{gathered} \frac{1yard}{3feet}=\frac{6.75yards}{?feet} \\ ?feet\times1yard=6.75yards\times3feet \\ ?feet=\frac{6.75yards\times3feet}{1yard} \\ 6.75yards=20.25feet \end{gathered}[/tex]Now, we will convert it to inches:
[tex]\begin{gathered} \frac{12inches}{1food}=\frac{?inches}{20.25feet} \\ \frac{12inches\times20.25feet}{1food}=?inches \\ so: \\ 20.25feet=243inches \end{gathered}[/tex]So the answer is that 6.75 yards are 243 inches.
