C. 11/2÷9/4

Step-by-step explanation:

This question can be solved using a rule of three.

In $2 + \frac{1}{4} = \frac{2*4 + 1}{4} = \frac{9}{4}$ hours, the tank loses $5 + \frac{1}[2} = \frac{5*2 + 1}{2} = \frac{11}{2}$ gallons. How much does it lose in an hour?

1 hour - x gallons

9/4 hours - 11/2 gallons

$\frac{9x}{4} = \frac{11}{2}$

$x = \frac{\frac{11}{2}}{\frac{9}{4}}$

So the correct answer is C.
