${\underline {\underline{ \bf{Given}}}}$

Jaidev takes 2 1/5 minutes and Rahul takes 7/4 minutes to walk the ground.

${ \underline{ \underline{ \bf{Asked : }}}}$

Who takes less time and by what fraction ?

${ \underline{ \underline{ \bf{operation}}}}$

Substraction (-)

${ \underline{ \underline{ \bf{TO \: FIND : }}}}$

Who takes less time and by what fraction,we compare and substract 2 1/5 and 7/4

2 1/5 - 7/4

Jaidev takes 2 1/5 minutes to walk.

Rahul takes 7/4 minutes to walk.

To find who takes less time and by what fraction,we compare and subtract 2 1/5 and 7/4.

${ \underline{ \underline{ \bf{solve \: problem : }}}}$

• Convert mixed fraction to improper fraction :-

2 1/5 = 11/5

• L.C.M. of the denominators (5 and 4) is 20.
• Convert the fraction to like fractions.

By finding equivalent fraction : 44/20 > 35/20

• Substract the smaller fraction from the bigger fraction.

44/20 - 35/20 =44 - 35/20 = 9/20

Therefore,Jaidev takes 9/20 more minutes to walk across the ground.

Answer 2

Answer:

44/20 - 35/20 =44 - 35/20 = 9/20
