enot [183]

Given :

Number of hours studied daily , $T=5\dfrac{2}{3}$ .

Time given for science and mathematics is , $t=2\dfrac{4}{2}$ .

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 .

$x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}$

Therefore , time devote for other subject is $1\dfrac{2}{3}$ hours .

Hence , this is the required solution .
