Question

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

Answer 1

Answer:

Step-by-step explanation:

Zenab can paint whole saree in 7 hours. This means in 1 hour Zenab can paint 1/7th saree. In 2 whole 1/2 hours he can paint 5/14th saree. He will paint 1/4th saree in 1 whole 3/4 hours.

Answer 2

Answer:

The portion of the saree Zenab can complete in 1 hour =$\frac{1}{7}^{th}$ of the saree

The portion of the saree she can do in 2$\frac{1}{2}$  hours = $\frac{5}{14} ^{th}$of the saree

The portion of the saree  she can do in $1\frac{3}{4}$  hours= $\frac{1}{4}{th}$of the saree

Step-by-step explanation:

Given,

The time required by Zenab to paint the whole saree = 7 hours

Required to find,

(i) The portion of the saree Zenab can paint in 1 hour

(ii) The portion of the saree Zenab can paint in 2$\frac{1}{2}$ hours

(iii) The portion of the saree Zenab can paint in 1$\frac{3}{4}$ hour.

Since the time required by Zenab to paint the whole saree = is 7 hours

The portion of the saree Zenab can complete in 1 hour =$\frac{1}{7}^{th}$ of the saree

The portion of the saree  she can do in 2$\frac{1}{2}$  hours = $2\frac{1}{2} X \frac{1}{7}$ th of the saree

= $\frac{5}{2} X \frac{1}{7}$th of the saree

= $\frac{5}{14} ^{th} of the saree$

The portion of the saree she can do in 2$\frac{1}{2}$  hours = $\frac{5}{14} ^{th} of the saree$

The portion of the saree  she can do in 2$\frac{1}{2}$  hours = $2\frac{1}{2} X \frac{1}{7}$ th of the saree

= $\frac{5}{2} X \frac{1}{7}$th of the saree

= $\frac{5}{14} ^{th}$of the saree.

The portion of the saree she can do in 2$\frac{1}{2}$  hours = $\frac{5}{14} ^{th}$of the saree

The portion of the saree  she can do in $1\frac{3}{4}$  hours = $1\frac{3}{4} X \frac{1}{7}^{th$of the saree

=$\frac{7}{4} X \frac{1}{7}^{th$ of the saree

=$\frac{1}{4} ^{th$ of the saree.

The portion of the saree  she can do in $1\frac{3}{4}$  hours= $\frac{1}{4}{th}$of the saree

Hence,

The portion of the saree Zenab can complete in 1 hour =$\frac{1}{7}^{th}$ of the saree

The portion of the saree she can do in 2$\frac{1}{2}$  hours = $\frac{5}{14} ^{th}$of the saree

The portion of the saree  she can do in $1\frac{3}{4}$  hours= $\frac{1}{4}{th}$of the saree
