Plss helpp with this

2:24

1:12

4:48

3:36

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.

ab will be equal to

i think asking google will you get the answer to that question
