A fish tank is three-fourths full.

max2010maxim [7]

Answer: $\frac{5}{12}$

Step-by-step explanation:

We will subtract the amount of water that leaked out from the amount of water originally in the fish tank.

$\displaystyle \frac{3}{4} - \frac{1}{3} =\frac{3*3}{4*3} -\frac{1*4}{3*4} =\frac{9}{12} -\frac{4}{12}=\frac{5}{12}$

The fish tank is $\frac{5}{12}$ of the way full.
