The number of hours to study 3 credit course is = 6hrs/ week.
The number of hours studied on monday, wednesday and friday,
= 3/5 + 16/4 +2/3
The lowest common multiple of the denominators 5, 4 and 3 = 60
= [tex]\frac{36 + 240 + 40}{60}[/tex]
= 316/60
Reduce to the lowest figure by dividing through with 4,
= 79/15
To detemine the extra hours to be studied over the weekend, subtract 79/15 from 6.
that is, 6/1 - 79/15
The lowest common multiple of denominators 1 and 15 = 15
= [tex]\frac{90 - 79}{15}[/tex]
= [tex]\frac{11}{15}[/tex] hrs
