Question

$1.8m$ of cloth is required for a shirt. How many such shirts can be made from a piece of cloth $45m$ long?

Answer 1

Cloth required for $1$ shirt $=1.8m$
$\therefore$ Number of shirts that can be made from $45m$ of cloth $=\frac{45}{1.8}$

$=\frac{450}{18}$

$=\frac{150}{6}$

$=\frac{50}{2}$

$=25$
Hence, $25$ shirts can be made from a piece of cloth of length $45m.$
