There are one thousdand students in Central High School. Three hundred twenty-eight of the students are seniors. Write the decimal that shows what part of the student body is in the senior class.

328 / 1000 = 0.328

To write the decimal that shows what part of the student body is in the senior class, you need to divide the number of seniors by the total number of students.

Step 1: Divide the number of seniors (328) by the total number of students (1000):

328 ÷ 1000 = 0.328

Therefore, the decimal that represents the part of the student body in the senior class is 0.328.
