Mohan had 3 hours of free time in the evening. He spent 45 minutes on home-work and 1 1/2 hours on games. How much free time was he left with? (Write the answer as a fraction.)
Answers
Total number of free time = T = 3 hours
Time spend on home work = t_1t
1
= 45 minutes
Time spend on games = t_2t
2
= 112 minutes

Or, T = t_1 + t_2 + t_3t
1
+t

+t
3
Or, t_3t

)
Or, t_3t

= 3 hours - ( 45 min + 112 min )
Or, t_3t
3
= 3 hours - ( 157 min )
Or, t_3t
3
= 3 × 60 min - 157 min ( ∵ 1 hours = 60 min )
Or, t_3t
3
= 180 min - 157 min
∴ t_3t
