Mimi picked up 2 dozen seashells on the beach.  Kyle found twice as many shells as Mimi and put them in his pocket. Leigh grabbed one-third of the shells that Kyle found.  How many seashells did Leigh have?
Mimi has 2 x 12 = <<2*12=24>>24 sea shells.
Kyle has 24 x 2 = <<24*2=48>>48 sea shells.
Leigh has 48 / 3 = <<48/3=16>>16 sea shells.
