Three hexagons comprise more than 7 lines so you cannot use only seven numbers, once each, to make all the lines add up to the same number!
A hexagon has six sides, so seven hexagons will have 6 * 7 = 42 sides.
Yes seven is a prime number and the only numbers that will go in to seven is one and seven.
you whole numbers that seven go in to
There is an infinite number of numbers that are not divisible by seven!
number of prime numbers which are in the seven times tables: 1 prime numbers are in the seven times tables: 7 only
The number of combinations of six numbers that can be made from seven numbers will depend on if you can repeat numbers. In all there are over 2,000 different numbers that can be made.
Yes.
7/8 is a rational number because rational numbers are fractions, numbers that terminate, numbers that repeat.
Mixed numbers can't be whole numbers.

Well, being that 7 is a prime number (only one and itself will go into it evenly), there are no other numbers that share all of the common factors of the number seven, and only those factors, but if you are asking what numbers share either or any of the common factors of seven, your answer would be, infinity. Because 1 will go into every other number except 0. I hope I'm understanding your question correctly.
