#### Answer

$6$ pieces of $2.75$-in cables can be cut from the $18.5$-in cable
$2$ inches of the original cable will be left.

#### Work Step by Step

To know how many cables $2.75$ inches long can be cut from the $18,5$-in long cable, divide $18.5$ by $2.75$ using long division to get $6.\overline{72}$.
Refer to the attached image below for the actual division.
Thus, 6 pieces of $2.75$-inch cables can be cut from the given $18.5$-in cable.
To know how much of the cable is left, subtract the total length of the 6 pieces of shorter cables from $18.5$ to obtain:
$=18.5 - 6(2.75)
\\=18.5 - 16.5
\\=2 \text{ ft}$
