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?
When Stefan cuts the rope into four equal parts, he gets 200/4 = <<200/4=50>>50 meters of each piece.
If he decides to subdivide each piece, he and up with 50/2 = <<50/2=25>>25 meters.
