Question

pink studies daily for 7/3 hours in the morning and 7/2hours in the evening while Divya studies for 13/4hours in the morning and 13/6hours in the evening when studies more and by how muc​

Answer 1

Step-by-step explanation:

pinky - 7/3 in morning

7/2 in evening

7/3 + 7/2

= LCM = 6

7/3X 2/2 + 7/2 X 3/3

= 14/6 + 21/6

14+21/6

=35/6

=5.83 hours

divya :

13/4 + 13/6

lcm - 12

13/4X3/3 + 13/6X2/2

= 39/12 + 26 /12

= 39+26 /12

= 65/12

= 5.416 hours

hence ,

5.830hours >5.416 hours

pinky studied more and by,

5.830hours-5.416 hours

= 0.414 mins

Answer 2

Answer:

for pink

total study time = 7/3 +7/2

= 14 + 21/6

= 35/6

for divya

total study time = 13/4 + 13/6

= 39 + 26 /12

= 65/12

diffrence = 35/6 -65/12

= 70 - 65/12

= 5/12

Hence, pink studies more by 5/12.
