Meiling has 1 1/4 liter of orange juice.

Express mixed fraction 1 1/4 into fraction :


\begin{gathered} 1(1)/(4)=(1*4+1)/(4) \\ 1(1)/(4)=(5)/(4) \end{gathered}

So,

Meiling has 1 1/4 liter of orange juice = 5/4 liter juice

She drinks 1/3 liter

Amount of juice used = 1/3 liter

Left juice = Total amount of juice - Amount of juice drank by Meiling

Left juice = 5/4 - 1/3


\begin{gathered} (5)/(4)-(1)/(3) \\ \text{ LCM of 4 \& 3} \\ (5)/(4)-(1)/(3)=(3*5-4*1)/(12) \\ (5)/(4)-(1)/(3)=(15-4)/(12) \\ (5)/(4)-(1)/(3)=(11)/(12) \end{gathered}

Amount of juice left is 11/12 liter

Answer : 11/12 liter
