Answer:
(C) - C for Correct!
Explanation:
We can look at ratios as a fraction, so 1:3 = 1/3 and 12:36 = 12/36. We can simplify the second fraction into 12/36 = 1/3 by canceling 12 from the numerator and denomerator. We can do this with all of the answer choices:
(A) Wrong - 2/18 = 1/9
(B) Wrong - 4/9
(C) Correct - 4/12 = 1/3
(D) Wrong - 6/6 = 1
I hope this helps!!! :)
