like the user sheshy said it:
Complete the number 7xxxxxx4x with the rest of the numbers in 1-9 so that any 2 adjecent digits in it are a result in the multiplication table.
i think his instruction is way clearer then mine, hope that helps : )

in math there are some basic multiplication operations, from 11,12,13,... till 109,10*10
every pair of adjecent numbers should be a result of these basic multiplication table
here as a picture:
also wikipedia
basic means there are ten collumns and ten rows in the table
i'm so sorry for the language barrier, but i really don't know how to say it in other words

so, the GAs are over, now i will post the solutions to the riddles
solution of the 1st one:
as you can see, there are 3 zeros, 2 ones, 1 two, 1 three and 0 fours, fives and sixes
solution of the 2nd one:
as many of you may have recocnized, this answer was very simple to bruteforce.
the right solution is to count the closed areas in the numbers, like in the seven examples
solution of the 3rd one:
this solution is true, because there are the numbers from 1 to 9 in the number and every
pair of 2 adjecent numbers (eg. 72, 81, 35, 63, ...) is an outcome of the basic multiplication table
thank you for playing
