Question

Hola Amigos! math Question,



Suman studies 5 2/3 hours daily he spend 2 4/5 hours for science and maths how much time does he spend for other subjects ​

Answer 1

Answer:

●☆Given:-

Total study time =5 2/3hours .

He spends for time for maths and science = 2 4/5 hours

Now ,

Time for other 4 subjects= 5 2/3-2 4/5

= [5+2/3]-[2+4/5]

= (5-2)-(2/3-4/5)

= 3+(10-12/15)

= 3+(-2/15)

= 3-2/15

= 3×15-2/15

=43/15

Since numerator >denominator

converting by mixed fraction we get

15)43 (2

30

13.

Therefore,

Time for other 4 subjects is 2 13/15hours .

Hope it helps u mate,

Thank you.

Answer 2

Step-by-step explanation:

Given :

Suman studies $\bold{5\frac{2}{3} }$ hours daily.

He spends $\bold{2\frac{4}{5} }$ hours for science and mathematics.

To find :

How much time does he spend for other subjects.

Solution :

We have,

=> Total time spent by Suman for studies :

• $\bold{5\dfrac{2}{3} }$ hours

=> Total time spent by Suman for science/mathematics :

• $\bold{2\dfrac{4}{5} }$ hours

To find,

=> Total time spent for other subjects ?

Time spent by Suman for studies :

=>  $\bold{5\dfrac{2}{3} }$

=> $\bold{\dfrac{17}{3} }$ hours

Time spent by Suman for science/mathematics :

=> $\bold{2\dfrac{4}{5} }$

=> $\bold{\dfrac{14}{5} }$ hours

Time spent by Suman for other subjects :

• Time spent by Suman for studies - Time spent by Suman for science/mathematics

=> $\bold{\dfrac{17}{3}-\dfrac{14}{5} }$

=> $\bold{\dfrac{17\times5-14\times3}{15} }$

=> $\bold{\dfrac{85-42}{15} }$

=> $\bold{\dfrac{43}{15} }$ or $\bold{2\dfrac{13}{5} }$ hours.
