$$\frac{2}{11}\times\frac{11}{2}=\frac{11}{2}\times\frac{2}{11}=1$$
$\text{true}$
$$1=\frac{11}{2}\times \frac{2}{11}\text{ and }\frac{11}{2}\times \frac{2}{11}=1$$
$$1=1\text{ and }\frac{11}{2}\times \frac{2}{11}=1$$
$$\text{true}\text{ and }\frac{11}{2}\times \frac{2}{11}=1$$
$$\text{true}\text{ and }1=1$$
$$\text{true}\text{ and }\text{true}$$
