I wrote, "Το κορίτσι έχει εκατό δολάρια στο πορτοφόλι της." and didn't accept. As the right one give me the :
"Το κορίτσι έχει στο πορτοφόλι της εκατό δολάρια."
Why is it wrong, I think that both are correct!
Both sentences are correct, either word order is fine. Could it be there was something wrong about your answer? Mixing up the two alphabets? Maybe the computer has directly displayed the main Greek translation then.
