    $\frac{1111}{2020}$ × $\frac{1212}{2121}$ × $\frac{1313}{2222}$ × $\frac{1414}{2323}$ × $\frac{1515}{2424}$ × $\frac{1616}{2525}$ × $\frac{1717}{2626}$ × $\frac{1818}{2727}$ × $\frac{1919}{2828}$
    = $\frac{11}{35}$ × $\frac{91}{253.}$ ×$\frac{2}{5}$ × $\frac{17}{39}$ × $\frac{19}{28}$ 
    =$\frac{13}{115}$ × $\frac{34}{195}$ ×$\frac{19}{28}$ 
    =$\frac{34}{1725}$ × $\frac{19}{28}$ 
    =$\frac{323}{24150}$
