Question

One-fifth part of a wooden log is to be divided into three equal pieces.
So, the length of each piece is part of the wooden log.

• A. $\frac{1}{15}$
• B. $\frac{3}{5}$
• C. $\frac{1}{5}$
• D. $\frac{5}{15}$

Answer 1

The correct option is A $\frac{1}{15}$

Part of the wooden log initially used = $\frac{1}{5}$

Now, it is to be divided into 3 parts.

$\therefore$ The length of each piece $=\frac{1}{5}÷3$
$=\frac{1}{5}÷\frac{3}{1}$
$=\frac{1}{5}\times \frac{1}{3}$
$=\frac{1\times 1}{5\times 3}$
$=\frac{1}{15}$

So, length of each piece will be $=\frac{1}{15}$
