121*1001001001001*12*10101010101/21*10101010101*212*1001001001001
=121*12/21*212=121*3*4/3*7*5*4=121/35=3又16/35

=(121121*1000001)/(212121*1000001)*(121212*100001)/(212212*1000001)
=121121/212121*121212/212212
=(121*101)/(21*10101)*(12*10101)/(212*101)
=(121)/(21)*(12)/(212)
=121*12/21/212
=121/7/53
=121/371

(121121121121/212121212121)*(121212121212/212212212212)
=(121*1001001001)/(21*10101010101)*(12*10101010101/212*1001001001)
=(121/21)*(12/212)
121/371
