Explanation:

Step1: Calculate students per class

To find the number of students per class, divide the total number of students by the number of classrooms. So, \(116\div4 = 29\).

Step2: Calculate dollars per lawn

To find the dollars per lawn, divide the total dollars by the number of lawns. So, \(51\div3=17\).

Step3: Calculate dollars per bar

To find the dollars per bar, divide the total dollars by the number of chocolate - bars. So, \(15\div5 = 3\).

Step4: Calculate words per minute

To find the words per minute, divide the total number of words by the number of minutes. So, \(450\div5=90\).

Step5: Calculate dollars per cover

To find the dollars per cover, divide the total dollars by the number of cell - phone covers. So, \(40\div8 = 5\).

Step6: Calculate cans per bag

To find the cans per bag, divide the total number of cans by the number of bags. So, \(141\div3=47\).

Step7: Calculate bags per truck

To find the bags per truck, divide the total number of bags by the number of mail - trucks. So, \(126\div9 = 14\).

Step8: Calculate books per box

To find the books per box, divide the total number of books by the number of boxes. So, \(63\div9=7\).

Step9: Calculate miles per hour

To find the miles per hour, divide the total number of miles by the number of hours. So, \(402\div6 = 67\).

Step10: Calculate cups per brownie

To find the cups per brownie, divide the total number of cups by the number of brownies. So, \(285\div95=3\).

Step11: Calculate customers per day

To find the customers per day, divide the total number of customers by the number of days. So, \(54\div2=27\).

Step12: Calculate customers per lane

To find the customers per lane, divide the total number of customers by the number of checkout - lanes. So, \(56\div4 = 14\).

Step13: Calculate ice - cubes per tray

To find the ice - cubes per tray, divide the total number of ice - cubes by the number of trays. So, \(20\div4=5\).

Step14: Calculate pints per container

To find the pints per container, divide the total number of pints by the number of containers. So, \(45\div3=15\).

Step15: Calculate dollars per student

To find the dollars per student, divide the total number of dollars by the number of students. So, \(72\div9 = 8\).
