Number 5 is ruled by planet Mercury and number 6 is ruled by planet Venus. Number 5 represents freedom, gambling, change, travel, adventure and demonstration. On the other hand, number 6 represents intelligence, intuition, loyalty, common sense and balance. Family is always a priority for the people of number 6. This association usually works well as both the partners have balanced characteristics in order to make a good family.
Both the people in this association need to make compromises for success in this relationship. They are incompatible in many aspects and therefore some suggest that this association might not be successful for business or marriage without making compromises. In a relationship, they would probably be good for each other if they could find a way to meet somewhere near the middle. They must avoid any tendency to become entrenched in positions which just won't work for the other.
