Answer 1

se observa ca  375375:375=1001    si 871871:871=1001
deci simplificam cu 1001

375375/871871 =375/871

(abc+bca+cab)/(xyz+yzx+zxy)=
=100a+10b+c+100b+10c+a+100c+10a+b)/100x+10y+z+100y+10z+x+100z+ 10x+y)=
=(111a+111b+111c)/(111x+111y+111)=111(a+b+c)/111(x+y+z)=
=(a+b+c)/(x+y+z)

ab0ab/17017 =(10000a+1000b+10a+b)/17 ×1001 =(10010a+1001b)/17×1001=
=1001(10a+b)/17×1001=(10a+b)/17
