Hello,

the container holds $\frac{3}{4}$ of 12 litres. This of is translated by "multiply!" with your sort of problems.

Therefore the container holds:
$\frac{3}{4} \cdot 12 = 9 \text{ litres}$ . Now there are poured off 4 litres. That means the final content is:
$9\text{ litres} - 4\text{ litres} = 5\text{ litres}$
