    Hi Nawaf, I think I got this:

    2) there are 387 Dvds and 154 Dvds are on loan. So that means 387 minus 154 will be the amount still left. so lets do it.
    387
    -154
    -----
    233
    But we have to put it to the nearest hundred. So
    233--->200

    200 are left, to the nearest hundred

    3) For number 3, there is not enough information, therefore it is not possible to get the answer. Nawaf, did you happen to forget the write the amount of books he has due? Because if you just say that one overdue library book is 75sc and s1.10 for another, I need to have more information.

    Hope this helps!
