Answer:
Step-by-step explanation: We have to add how much time it took him to do all of his homework. To do this, we have to add 2/3 and 3/5. 
First, we have to find a LCM between 3 and 5.
The LCM between those numbers are 15.
 Next we find out what number to multiply 3 by to get 15, we multiply it by 5.
2 * 5 = 10 
3 * 5 = 15
Next we find out what number to multiply 5 by to get 15, we multiply it by 3.
3 * 3 = 9
5 * 3 = 15
10/15+9/15=19/15
We are left off with 1 4/15
So it took him 1 hour and 4/15 minutes to do his homework.
