a 210 ft. long rope is cut into 3 pieces. the first piece of rope is 3 times as long as the second rope. the 3rd piece of rope is 2 times as long as the second piece of rope. What is the lenght of the longest piece of rope?

Let x = 2nd Rope, then 3x = first and 2x = third.
x + 3x + 2x = 210
Solve for x. 
35
