If a:b = 5:8, x:y = 25:16, evaluate a/x : b/y ?
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.
