Approximately 4 out of every 10 students at Sonia's college live on campus. The college has 3,000 students. How many of them live on campus?

if gloria received a 5 percent raise and is now making 25,200 a year what was her salary before the raise

To find out how many students live on campus, we need to calculate 4 out of every 10 students given that there are a total of 3,000 students at Sonia's college.

Step 1: Calculate the number of students as a fraction of the total number of students.
4 out of every 10 students can be expressed as a fraction as 4/10.

Step 2: Multiply the fraction by the total number of students.
Multiply the fraction (4/10) by the total number of students (3,000).

(4/10) x 3,000 = 1,200

Therefore, there are approximately 1,200 students who live on campus at Sonia's college.
