Answer:
science = 
English = 
Math = 4 hours
Step-by-step explanation:
let the number of hours spend on science = x
Hence the number of hours on English will be = 2x
Given that the number of hours spend on science is one third of the time spend on maths. Hence the time spend on math is 3 times that of the time spend on science. That the time spend on maths is = 3x
Hence the total time to study is
x+2x+3x
which is given as 8 hours
Hence
x+2x+3x =8
6x=8
dividing both sides by 6



Hence the number of hours foe studying science = 
Number of hours to study English =
=
Number of hours to study Math=
=
The first and last one are similar
Divide 24 by 4 because the denominator is 4..
24÷4=6
Multiply 6 by 3 because the numerator is 3.
6×3=18

As it appears to be the same thing on both sides so far wouldn't you think that it's 8?
