Answer:The answer is option (a)

Step-by-step explanation: For this question, since all 3 terms have the same power, you compare the bases and ignore the powers. So you have 3/5 × 15/10 = x/y. That is 45/50 = x/y. Reducing to the lowest terms 9/10 = x/y. I hope that helped.

Answer:

(a)

Explanation:

Since all ratios are raised to the power of 4, then


(x)/(y)

=
(3(15))/(5(10))

=
(45)/(50) =
(9)/(10) → (a)
