There are 4 seventh grade teachers at Central Middle School. Mr. Abbott teachs 120 students in 6 classes, Mrs. Garcia teaches 48 students in 3 classes. Ms. Ngyen's 5 classes total 109 students, and Ms. Turner has a total of 121 students in 6 classes. What is the average number of students in each seventh-grade math class?
Abbot with 120:6 Garcia with 48:3 Nguyen with 109:5 Turner with 121:6 Just add the number of students together and divide that by the amount of total classes and that is your answer. 120+48+109+121=398 and the classes 6+3+5+6=20 so your average is 398/20 which is 19.9 so 20 people per class because there can't be .9 of a person in class.
