We know that there are 99 students in total. He already entered the marks of 9/11 of the students. We need to find out how many students’ marks have not been entered yet.

We can multiply 99 by 9/11. This gives us 81. We now need to subtract 99 from 81. This gives us 18.

He has not entered the marks of 18 students.
