Step-by-step explanation:

First, you want to find the unit rate for teachers (since you can't have 1/2 of a person/teacher). You do this by dividing 12 and 2 by 2, because there are 2 teachers teaching a class of 24.

24 divided by 2 = 12

2 divided by 2 = 1

Therefore 1 teachers teaches 12 students.

1:12 is the first ratio

You can find the second one by doing 12 times 4, because if each teacher gets 12 students, and there are 4 teachers, you need to add 12+12+12+12 or just 12 times 4.

4:48

For 36 you need to do the reverse. 36 divided by 12, because if there are 12 students for 1 teacher, finding how many times 12 fits into 36 will give you the number of teachers you have.

3:36

Remember when doing problems like this to also use your logic. For instance, you can't have 1 and 1/2 teachers or 15 and 1/4 students.

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
