Juan has a piano next month . last week he practiced for 8 hours in the morning and 7 hours in the afternoon. each practice session is 2 hours long. how many full practices session did juan complete?

First of all we will divide 8 by 2 to get the number of full practices in the morning, which is 4. Next divide 7 by 2 to get the number of practices in the afternoon. Although there is a remainder, that remainder is not a full practice session, so we only count the whole numbers which is 3. 
4 + 3 = 7 full practice sessions.
