    Do one's duty to/with/by smb?

    Please help me to fill in the following blanks with the correct preposition:

    • I have always done my duty ___ my students.

    I am extremely confused about this sentence. The key says "to", my teacher says "with" but I'd rather "by".
    • The boy was called ___ by his grandfather.

    I think the sentence means that his grandfather named the boy. I've looked up the dictionary for the phrasal verb of call meaning as name but found nothing.

    • These are sold ___ five selling each.

    I would fill with "by". But my teacher fills with "at". She says that selling is an monetary unit like $. Yet, I have never known any monetary unit called selling

    * I have always done my duty ___ my students.

    I am extremely confused about this sentence. The key says "to", my teacher says "with" but I'd rather "by". I like "for" here.

    * The boy was called ___ by his grandfather.
    In this case, I think "called" means "summoned."

    These are sold ___ five selling each.
    This one doesn't make any sense to me.

    So what preposition would you fill in this blank with?
