Answer:
She tutors 8 students
Step-by-step explanation:
She is at the library for 6 hours. One hour has 60 minutes so she is at the library for [tex]6*60=360[/tex] minutes.
She helps each student for [tex]3/4[/tex] of an hour, that means [tex]3/4*60=45[/tex] minutes.
So now we have to calculate how many times does 45 minutes fits in 360 minutes (how many students she can help in 6 hours). That is [tex]360/45=8[/tex] students.
