Question

Jaidev takes 2(1/5) minutes to walk across the school ground. Rahul takes(7/4) minutes to do the

same. Who takes less time and by what fraction?
​

Answer 1

Firstly, let us convert the time taken by Jaidev in improper fraction from mixed fraction

$2 \times \frac{1}{5} = \frac{10 + 1}{5 } = \frac{11}{5}$

Now, comparing both, we have :

$\frac{7}{4} < \frac{11}{5}$

Also,

$\frac{11}{5} \ - \frac{7}{4} = \frac{11 \times 4 - 7 \times 5}{20} = \frac{9}{20}$

Hence Rahul takes less time as compared to Jaidev by

$\frac{9}{20}$

fraction.

Answer 2

Step-by-step explanation:

Time taken by Jaidev = \frac{11}{5}  

5

11

​  

 minutes

Time taken by Rahul = \frac{7}{4}  

4

7

​  

 minutes

Difference = \frac{11}{5}-\frac{7}{4}=\frac{\left(11\times4\right)-\left(7\times5\right)}{20}=\frac{44-35}{20}=\frac{9}{20}
