Answer:
Answer choice A
Step-by-step explanation:
Whenever you divide something by a fraction, you can rewrite that as multiplying by the reciprocal. In other words, [tex]\frac{240+55x}{x}\div \frac{270+35x}{x}=\frac{240+55x}{x}\cdot\frac{x}{270+35x}=\frac{x(48+11x)}{x(54+7x)}=\frac{48+11x}{54+7x}[/tex], or answer choice A. Hope this helps!
