Question

A girl studied for 5 2/3 hours daily. She devotes 2 4/2 hours of her time for science and mathematics. How much time does she devote for other subjects?

Answer 1

Given :

Number of hours studied daily ,
`T=5(2)/(3)` .

Time given for science and mathematics is ,
`t=2(4)/(2)` .

To Find :

How much time does she devote for other subjects .

Solution :

Let , time devote for other student is x .

So , Time left for other subject = Total time - Time taken by science and mathematics .

`x=T-t\\\\x=5(2)/(3)-2(4)/(2)\\\\x=((5* 3)+2)/(3)- ((2* 2 )+4)/(2)\\\\x=(17)/(3)-4\\\\x=(17-(4* 3))/(3)\\\\x=(5)/(3)=1(2)/(3)`

Therefore , time devote for other subject is
`1(2)/(3)` hours .

Hence , this is the required solution .
