A college has 1200 students. If 60% of them are girls, how many boys are there?

Step 1: Find out how many girls are in the college by calculating 60% of 1200 students.
Step 2: To calculate 60% of 1200, multiply 1200 by 0.6 (which is the decimal form of 60%).
Step 3: The result of 0.6 * 1200 is 720. This means there are 720 girls in the college.
Step 4: To find out how many boys are in the college, subtract the number of girls from the total number of students.
Step 5: So, subtract 720 (girls) from 1200 (total students): 1200 - 720 = 480.
Step 6: Therefore, there are 480 boys in the college.
