Answer 1

Subtract 1/2 - 2/11;

`\begin{gathered} (1)/(2)-(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,} \\ (11)/(22)-(4)/(22) \\ =(11-4)/(22) \\ =(7)/(22) \end{gathered}`

The answer is 7/22
