**A.** 2:5

**B.** 125:128

** C.** 3:5

**D.** 3:4

**QUICK ANSWER…**

**A**

**DETAILS…**

**Pretty straight forward question, we’re going to solve this with the simplest method as follows:**

**From the question, you can safely say:**

**a = 5**

**b = 8**

**x = 25**

**y = 16**

**therefore, a/x = 5/25 = 1/5**

**also, b/y = 8/16 = ½**

**finally,**

**a/x : b/y**

**= 1/5 : ½**

**= ****⅕ ÷ ½ **

**= ****⅕ ×**** 2/1**

**= 2/5**

**= 2:5 = option A**

**Now for the right answer to the above question:**

**Option A is correct.****Option B is incorrect.****C is not correct.****D is not the correct answer.**
