Step-by-step explanation
Given that: Carmela says that 3/6 is more than 2/3 because 3 pieces are more than 2 pieces
I will disagree with Carmela because
If we use the principle of equivalent fraction

So instead, Carmela should have compared

From the above

Thus, 2/3 is actually greater than 3/6
Carmela is wrong because she took the wrong approach to determine the greater value
