Let the length of the two piece be x each
Cut a length of y from one piece
The remaining length = x - y
The length of one piece is the average of the other two
y = (x + x - y)/2
2y = 2x - y
3y = 2x
x/y = 2/3
The other piece is cut in the ratio: 2 : 3
Cut a length of y from one piece
The remaining length = x - y
The length of one piece is the average of the other two
y = (x + x - y)/2
2y = 2x - y
3y = 2x
x/y = 2/3
