how do i fine the answer to 1/11 divide by 11/1

$$\\\frac{1}{11}\div \frac{11}{1}\\\\
=\frac{1}{11}\times \frac{1}{11}\\\\
=\frac{1}{121}$$

.

$$\left({\frac{{\mathtt{1}}}{{\mathtt{11}}}}\right){\mathtt{\,\times\,}}\left({\frac{{\mathtt{1}}}{{\mathtt{11}}}}\right) = {\frac{{\mathtt{1}}}{{\mathtt{121}}}} = {\mathtt{0.008\: \!264\: \!462\: \!809\: \!917\: \!4}}$$
