Answer:

7⅓ feet

Step-by-step explanation:

The length of wire bought by the workers = 2 4/9 feet

Since the construction manager said they need 3 times that amount.


\text{The length of wire they need}=3*2(4)/(9)

We simplify by first changing the mixed fraction to an improper fraction.


\begin{gathered} =3*(22)/(9) \\ =(22)/(3) \\ =7(1)/(3)\text{ feet} \end{gathered}

They need 7⅓ feet of wire.
