Question

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?

A.
Yes

B.
No, because 64 ÷ 8 = 8 and 72 ÷ 8 = 9, so the answer should be between 8 and 9.

C.
No, because 70 + 8 = 78, and Maria has less than 70 inches of ribbon, so the answer should be a bit less than 78.

D.
No, because 70 • 8 = 560 and Maria has less than 70 inches of ribbon, so the answer should be a bit less than 560.
