Given that :
Jack had 4 hours of school.
He spent 45 minutes in the library
1/2 hour on a science lecture and;
had a lunch break of 25 minutes
The objective is to determine how much time is left for the school to get over and we are to write the answer as a fraction.
In order to do that, we will have to convert the minutes into hours,
we all know that; 60 minutes = 1 hour.
Then,
45 minutes = (45/60)hour = 3/4 hour
25/60 minutes = 1/4 hour
Therefore, the amount of time left for the school to get over is:
= 
= 
= 
=
