amena ate 1-2 of a sandwich amena said they ate the same amount Lavonne said amena ate more could lavonne be correct explain your thinking

Answers

Amena ate 1/2 of a sandwich, and said that her an Lavonne ate the same amount, but Lavonne argued that Amena ate more.

If Amena ate 1/2 of the sandwich, then there is only 1/2 of the sandwich left, as 1 - 1/2 = 1/2.  Therefore, Lavonne couldn't have eaten more of the sandwich than Amena, because there isn't enough of the sandwich left for that.

Lavonne is incorrect.
