will i get marks in boards if i leave my ans in fraction in the chapter area related to circles

Dear student, CBSE gives marks for the steps, but that's also dependable, if it's 1-2 marks question they might want you give the complete answer and if it's 4-6 marks question they might give you marks for the steps. So it's better to answer the question completely and if it is a school exam then marks for the steps depends all on you subject teacher.
