Total students in the 6 classes: 19 + 13 + 19 + 9 + 14 + 15 = 89

Average class size = 89 ÷ 6 = 14.8

We find the average by adding up all the students and dividing them by the number of classes she has. 19 + 13 + 19 + 9 + 14 + 15 is 89, and that divided by 6 is approximately 14.8, rounded to the nearest tenth.
