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
