Answer:

Number of students who got grade A =
(8y)/(x)

Explanation:

Number of students who got grade B = 8

Ratio of the students that got A to the students who got B =
y:x

That is

Number of students who got grade A : Number of students who got grade B =


y:x

Number of students who got grade A : 8 =
y:x

Therefore,

Number of students who got grade A =
(8y)/(x)
