We can change the statement into a question as follows; Am I sending you money?
How to change a statement to a question
We can change statements to questions with the aid of question marks and an understanding of what the rephrased form of the sentence is. So, in the original statement, the speaker says that they are sending money to the receiver of the information.
To change this statement into a question, they would then say; Am I sending you money? The question mark at the end of the second statement shows that this is a question. Thus, we have changed the statement into a question.
