Question

what portion of a saree can zenab paint in one hour if it requires 7 hours to paint the whole saree? in 2 1 2 hours? in 1 3 4 hours? ​

Answer 1

Zenab take 7 hrs to paint saree=1 saree

$\small \bold{Zenab \: take \: 1 \: hr \: to \: paint \: saree= \frac{1}{7} }$

$\small{Zenab \: take \: 2 \frac{1}{2} \: hrs \: to \: paint \: saree}$

$= \frac{1}{7} \times 2 \frac{1}{2} \: hours$

$= \frac{5}{14} \: the \: saree$

$Zenab \: take \: 1 \frac{3}{4} \: hrs \: to \: paint = \frac{1}{7} \times 1 \frac{3}{4} \: saree$

$= \frac{1}{7} \times \frac{7}{4}$

$= \frac{1}{4} \: the \: saree$
