Question

A wire of length $12\frac{1}{2}$m is cut into 10 pieces of equal length. Find the length of each piece.

• A. $1\frac{1}{4}m$
• B. $\frac{4}{5}m$
• C. $\frac{6}{5}m$
• D. $1\frac{3}{4}m$

Answer 1

The correct option is A $1\frac{1}{4}m$

Length of wire = $12\frac{1}{2}m$
Wire is cut into 10 pieces.

$12\frac{1}{2}=\frac{25}{2}\text{as an improper fraction}$

Length of each piece of wire
$=\frac{25}{2}÷\frac{10}{1}$

$=\frac{25}{2}\times \frac{1}{10}$

$=\frac{25}{20}=\frac{5}{4}=1\frac{1}{4}m$
