Answer:
The greatest possible length of the pieces is 5 feet
Step-by-step explanation:
Red = 415 feet
Green = 780 feet
Find the greatest possible length of the pieces.
Find the Highest common factor
415 = 1, 5, 83, 415
780 = 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390 and 780
The Highest common factor of 415 and 780 is 5
The greatest possible length of the pieces is 5 feet
Red = 415/5
= 83 pieces
Green = 780/5
= 156 pieces
