The 120foot rope is cut into 3 pieces.The first of rope is twice as long as the second piece of rope.The third piece of rope is three times as long as the second piece of rope.What is length of the longest piece of rope.

second piece  x ft
first piece  2x feet
third piece  3x
solve x + 2x + 3x = 12 
first piece is 2X
second piece is X
third piece is 3X
solve : X+2X+3X=120
once you solve for X, then just plug it in.
