<human>:  A rope has a length of 200 meters. Stefan cuts the rope into four equal parts, gives his mother half of the cut pieces, and subdivides the remaining pieces into two more equal parts. What's the length of each piece?
<bot>: How many meters does each piece have? ** When Stefan cuts the rope into four equal parts, he gets 200/4 = <<200/4=50>>50 meters of each piece.
How many meters does each piece have after subdivision? ** If he decides to subdivide each piece, he and up with 50/2 = <<50/2=25>>25 meters.
