Question

$42$ meters of cloth is required to make $20$ shirts of the same size. How much cloth will be required to make $36$ shirts of that size.

Answer 1

Total cloth required to make $20$ shirts $=$$42$ meters

Divide both side by $20$

Total cloth required to make $1$ shirt $=$$\frac{42}{20}$meters

Multiply both side by $36$

Total cloth required to make $36$ shirt $=$$\frac{42}{20}\times 36=75.6$ meters

Hence, $75.6$ meters cloth will be required to make $36$ shirts of that size.
