Approximately 3 out of every 10 students at Greg's college live on campus. The college has 6,000 students. How many of them live on campus?

A)

To find out how many students live on campus, we need to determine what fraction of the students live on campus and then multiply it by the total number of students.

The fraction is given as 3 out of 10. To convert this into a decimal, we divide 3 by 10: 3 รท 10 = 0.3

Now, we can multiply this decimal by the total number of students: 0.3 x 6,000 = 1,800

Therefore, approximately 1,800 students live on campus.
