Question 235391
Let x be the length of the first piece.
3x is the length of the second piece.
5x is the length of the third piece.
x+3x+5x=333
9x=333
x=333/9
x=37 inches is the length of the first piece.
3*37=111 inches is the length of the second piece.
5*37=185 inches is the length of the third piece.
Proof:
37+111+185=333
333=333
