Question

ur frnd often insists that you do your homework together but they copy

Answer 1

Self help is the best help. Let them do their homework on their own. You don't show your homework to them and let them copy by making them lazy. Then they won't learn anything but just inherit the habit of copying and even in exams. So friend don't ever do this mistake! Instead help them who don't understand some problems and have doubts not the lazy one who does nothing rather than copying yours.
Thanks

Answer 2

Copying answer is a very big problem for students.. they copy answer and when their exam comes. they fail because they can't copy answer in exam. 

We can convince them that copying answer is not good , it will affect your marks in exams, it is better to write wrong answer by own than copying right because atleast this will help our brain to develop.

Writing answers by own makes our brain more develop and creative.

And parents should also be careful that their sons/daughters are copying or not.
