molly is wrapping up parts of sandwiches to sell at her sandwiches cart. she cuts each sandwich in fourths and the wraps each fourth separately. she says that she wrapped 16 fourths so she wrapped 16 whole sandwiches. what Molly's mistake?
Molly didn't multiply 16 by 4. Since she's cutting EACH WHOLE sandwich in fourths and said that she wrapped 16 WHOLE sandwiches, you would have to multiply. I hope this helps!
