Answer:
Number of students who got grade A = [tex]\frac{8y}{x}[/tex]
Step-by-step explanation:
Number of students who got grade B = 8
Ratio of the students that got A to the students who got B = [tex]y:x[/tex]
That is
Number of students who got grade A : Number of students who got grade B =
[tex]y:x[/tex]
Number of students who got grade A : 8 = [tex]y:x[/tex]
Therefore,
Number of students who got grade A = [tex]\frac{8y}{x}[/tex]
