Ali bought 2

Ali bought 5/6 litre of milk. He drank 1/2 litre and his brother drank 1/6 litre. How much litre of milk left?

Correct answer:

x =  0.1667 l

Step-by-step explanation:

$$\begin{gathered} m={\displaystyle \frac{5}{6}}\doteq 0.8333\text{ l } \\ a={\displaystyle \frac{1}{2}}=0.5\text{ l } \\ b={\displaystyle \frac{1}{6}}={\displaystyle \frac{1}{6}}\doteq 0.1667\text{ l } \\ x=m-(a+b)=0.8333-(0.5+0.1667)=0.1667\text{ l} \end{gathered}$$
