Zach solved this problem.
Maria had a spool of ribbon 68 inches long. She cut the ribbon into 8 equal-length pieces. How long was each piece of ribbon?
Zach said the answer was 0.85 inches.
Is Zach's answer reasonable?
No, because 64 ÷ 8 = 8 and 72 ÷ 8 = 9, so the answer should be between 8 and 9.
No, because 70 + 8 = 78, and Maria has less than 70 inches of ribbon, so the answer should be a bit less than 78.
No, because 70 • 8 = 560 and Maria has less than 70 inches of ribbon, so the answer should be a bit less than 560.
