STatiana [176]

Answer:

Option A) $\frac{4x+3y}{3x-4y}$

Step-by-step explanation:

The given expression is:

$\frac{\frac{x}{3}+\frac{y}{4}}{\frac{x}{4}-\frac{y}{3}}$

Taking LCM in upper and lower fractions, we get:

$\frac{\frac{x}{3}+\frac{y}{4}}{\frac{x}{4}-\frac{y}{3}}\\\\ =\frac{\frac{4x+3y}{12}}{\frac{3x-4y}{12}}\\\\\text{Cancelling out the common factor 12, we get:}\\\\ =\frac{4x+3y}{3x-4y}$

Therefore, the option A gives the correct answer.
