x/y = 4/3 ~ 1.3
y/x = 3/4 ~ 0.7

Key concept: The ratio of x to y = x/y (same concept, different notation)
So, the question is really asking us to compare the following quantities:
QUANTITY A: x/y
QUANTITY B: y/x
Given: 3x = 4y
Divide both sides by y to get: 3x/y = 4
Divide both sides by 3 to get: x/y = 4/3
If we flip (invert) both fractions, we also get: y/x = 3/4
We get:
QUANTITY A: x/y = 4/3
QUANTITY B: y/x = 3/4
Answer: A
Cheers,
Brent
