Answer:
C. 11/2÷9/4
Step-by-step explanation:
This question can be solved using a rule of three.
In [tex]2 + \frac{1}{4} = \frac{2*4 + 1}{4} = \frac{9}{4}[/tex] hours, the tank loses [tex]5 + \frac{1}[2} = \frac{5*2 + 1}{2} = \frac{11}{2}[/tex] gallons. How much does it lose in an hour?
1 hour - x gallons
9/4 hours - 11/2 gallons
So
[tex]\frac{9x}{4} = \frac{11}{2}[/tex]
[tex]x = \frac{\frac{11}{2}}{\frac{9}{4}}[/tex]
So the correct answer is C.
