Question

The workers bought 2 4/9 feet of wire to instsll some speakers. The construction manger said they need 3 times that amount. How much do they need?

Answer 1

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.
