Answer:
The new class average for number of siblings is 3 5/26 or 3.1923
Step-by-step explanation:
if the average is 3 siblings per student and there are 25 students, it means that we can calculate the number of siblings
25 * 3 = 75
we add the 8 new siblings and we also add the student
75 + 8 = 83
25 + 1 = 26
To find the new average of siblings per student, we divide the number of siblings by the number of students.
83 / 26 = 3 5/26
the new class average for number of siblings is 3 5/26 or 3.1923
