Question

Molly is wrapping parts of sandwiches to sell at her sandwich cart . She cuts each sandwich in fourths and then wraps each fourth separately. She says that she wrapped 16 fourths, so she wrapped 16 hole sandwiches. What was Molly's mistake?

Answer 1

Assuming Molly has done as she said, and has cut each sandwich into fourths, and has in fact wrapped 16 fourths separately:

She has then wrapped $\frac{16}{4} = 4$ whole sandwiches, not $16$.

Answer 2

It depends on your definition of sandwich.

If a sandwich consists of two pieces of bread with something in between them, then cutting a sandwich into four parts creates four smaller sandwiches.

With this definition, Molly is correct.

If cutting a sandwich into parts does not create multiple sandwiches (you may need to come up with a term for what these are), then Molly is wrong.
