1) x = 2 and y = 3: 12 students got an A.
2) x = 4 and y = 3 6 students got an A. (from the comments)
Step-by-step explanation:
Hopefully I read this right, but the ratio you’re trying to find is A : B = y : x
1) Plug in x = 2 and y = 3 to get 3 : 2. Because we know 8 students got a B we’re going to multiply by 4 on each side to get 12 : 8 (12 A students and 8 B students).
2) You asked this in the comments so I answered it as well. Do the same thing as 1):
Plug in x = 4 and y = 3 to get 3 : 4.
We know there’s 8 B students so multiply by 2 to get 6 : 9. 6 A students and 9 B students.

2. If x is 2 and y is 3, the number of students that goat an A is 12.

### What are ratios?

Ratio expresses the relationship between two or more numbers. It shows the frequency that one value is contained within other value(s).

### How many students got an A?

In order to determine this, divide 8 by 2: 8/2 = 4
Multiply 4 by 3 = 12
