Question

If as many $7$-inch pieces of wire as possible are cut from a wire that is $3$ feet long, what is the total length of the wire that is left over? $(12inches=1foot)$

• A. $1$ inch
• B. $2$ inches
• C. $3$ inches
• D. $4$ inches
• E. $5$ inches

Answer 1

Answer: (A)

$1$ inch

Since $1foot=12inches$ therefore, $1feet=36inches$

we divide $36$ by $7$ we get remainder $1$

Therefore, the the total length of the wire that is left over is $1$ inch.

Hence option A is correct.
