$\frac{-18}{11}\text{ from }1$

Answer
$\frac{-18}{11}\text{ from }1$$\frac{1}{1}=\frac{1\times11}{1\times11}=\frac{11}{11}$
$\therefore1-\Big(\frac{-18}{11}\Big)=1+\frac{18}{11}$
$\frac{11}{11}+\frac{18}{11}=\frac{11+18}{11}=\frac{29}{11}$
$\therefore1-\Big(\frac{-18}{11}\Big)=1+\frac{18}{11}$
$\frac{11}{11}+\frac{18}{11}=\frac{11+18}{11}=\frac{29}{11}$
