A group charters 3 identical buses and occupies 4/5 of the seats. After 1/4 of the passengers leae, the remaining passangers use only 2 of the busses what fraction of the seats on the two buses are now occupied?
assume number of seats on all buses is 3x and in one bus x. how do you solve??

The number of passengers after 1/4 leave is
(3/4)(4/5)3x = 9x/5 = 1.8 x
The capacity of two buses is 2x
The fraction of seats occupied is
1.8x/2x = 9/10
