###Human: Barbie and Bruno have a pile of 144 coconuts that they need to move from one side of their yard to the other side.  Barbie can carry 4 coconuts at a time, while Bruno can carry 8 coconuts at a time.  If they make trips together carrying their maximum number of coconuts each time, how many trips together would they need to make to move all of the coconuts?, ### Assistant: Together, they would carry a combined total of 4+8=12 coconuts per trip.
To move 144 coconuts, they would need to make 144/12=12 trips. 
 So the answer is :  12
