Answer:

science = \frac{4}{3} \ hours

English = \frac{8}{3} \ hours

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

\frac{6x}{6}=\frac{8}{6}

x=\frac{8}{6}

x=\frac{4}{3}

Hence the number of hours foe studying science = \frac{4}{3}

Number of hours to study English = \frac{4}{3} \times 2=\frac{8}{3}

Number of hours to study Math= \frac{4}{3} \times 3=4
