Thank you for the opportunity to help you with your question!

Let's call the first piece of rope is X foot. 

2nd piece of rope is 2X foot. 

3rd piece of rope is 3X foot

but we know that, total length of rope is 120 foot

X+2X+ 3X= 120


X = 20 foot  i.e first piece of rope

2X = 2*20 = 40 i.e 2nd piece of rope

3X = 3*20 = 60 i.e 3rd piece of rope


First Piece = 20 foot

2nd Piece = 40 foot

3rd Piece = 60 foot   [Longest Piece of Rope]

we can also check that after adding all the pieces i.e 20+40+60 = 120 foot long. i.e original rope length

Please let me know if you need any clarification. I'm always happy to answer your questions.
