Question

William Arcenio is remodeling his home. In order to save​ money, he is upgrading the plumbing himself. He needs 18 pieces of copper​ tubing, each 2/9 of a foot long. If he has a 2​-foot piece of​ tubing, will that be​ enough? How much more does he need or how much tubing will he have left​ over?

Answer 1

Explanation:

If we have 18 pieces of
`(2)/(9)` ft tubing, then we need
`18 * (2)/(9) = 4` ft of tubing.

Since we only have 2 feet of tubing, we will need 2 more feet.

Answer 2

He needs 2 feet more tubing.

Explanation:

William Arcenio needs 18 pieces of copper​ tubing, each 2/9 of a foot long.

So, total length needed =
`(2)/(9)*18` = 4 feet

He has a 2​-foot piece of​ tubing.

So, he does not have enough tubing.

He needs 2 feet more tubing.
