A. x/y > 3/2
B. x/y < 2/3
C. x > 3y/2
D. x < 3y/2
E. 2x > 3y
On Multiplying both sides by \(-1\), the sign would flip
So,
\((-2x)(-1) > (-3y)(-1)\)
\(2x < 3y\)
\(x < \frac{3y}{2}\)
Hence, option D

Take: −2x > −3y
Divide both sides by -2 to get: x < 3y/2 [since we divided by a NEGATIVE value, we reversed the direction of the inequality symbol]
Answer: D
