Question

A piece of cloth is $5m$ long. After washing it shrinks by $\frac{1}{25}$ of its length. What is the length of the cloth after washing?

Answer 1

Length of the piece of cloth$=5m$

After washing the $5m$ cloth shrinks to $\frac{1}{25}\times 5=\frac{1}{5}m$

Lenth of the cloth after washing$=$Length of the cloth$-$Length of the cloth shrinked

$=5-\frac{1}{5}=\frac{25-1}{5}=\frac{24}{5}=4.8m$
