Răspuns :
ababab : ab =
100000a + 10000b + 1000a + 100b + 10a + b : 10a + b =
101010a + 10101b : 10a + b =
10101 x ( 10a + b ) : 10 a + b =
10101 x 1 =
10101
ababab=100000a +10000b+1000a+100b+10a+b=
10000(10a+b) +100(10a+b) +(10a+b)=(10a+b)(1000+100+1)= 10101(10a+b)=
=10101* ab
atunci 10101* ab:ab = 10101
