Answer:

7/33

Step-by-step explanation:

x = 0.21212121.... 2 digits in the repeating sequence, x 100 both side

100 x = 21.21212121...

100x - x = 21.21212121... - 0.21212121.... = 21

99x = 21

x = 21/99 = 7/33

The two regular hexagons could have different side lengths, so they will not necessarily always be congruent, but they will always be similar.
