Subtract 1/2 - 2/11;

$\begin{gathered} \frac{1}{2}-\frac{2}{11} \\ \text{The first step is to take the LCM of both denominators} \\ \text{The lowest common multiple of 2 and 11 is 22} \\ \text{Therefore, we now have,} \\ \frac{11}{22}-\frac{4}{22} \\ =\frac{11-4}{22} \\ =\frac{7}{22} \end{gathered}$

The answer is 7/22
