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

Answer:

7⅓ feet

Explanation:

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

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

$\text{The length of wire they need}=3\times2\frac{4}{9}$

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

$\begin{gathered} =3\times\frac{22}{9} \\ =\frac{22}{3} \\ =7\frac{1}{3}\text{ feet} \end{gathered}$

They need 7⅓ feet of wire.
