Answer 1

Suman studies for 5 2/3 hours daily. She devotes 2 4/5 hours of her time for Science and Mathematics. How much time does she devote for bother subjects?

Answer 2

Answer:

2 13/15 hrs

Step-by-step explanation:

5 2/3 = 17/3 hours

for maths and science 2 4/5 = 14/5 hours

for other subjects 17/3 - 14/5 =((17×5) - (14×3)) / 15

= (85 - 42) / 15

= 43/15 hrs

= 2 13/15 hours
