Hello,

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

Therefore the container holds:

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

$\displaystyle 9\text{ litres} - 4\text{ litres} = 5\text{ litres}$
