All numbers have an infinite amount of multiples.

Just take any magic square, and multiply every number by 5. Here you will get another magic square with all numbers multiples of 5.
Just 72.
It's 72
They are all multiples of 1.
The common multiples of a number with itself are the multiples of that number. Thus all multiples of A between 1 and 100 are the common multiples of A and A between 1 and 100.
100 divides into all the multiples of 100, which are infinite.
what is the ratio of multiples of 3 between 1 and 100 to all numbers between 1 and 100
All of those numbers have an infinite number of multiples.
I presume you mean what are all the multiples of 9 up to 100 (and not what are all the multiples of 9, 10, 11, ..., 100 of which there are infinitely many): 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.
There are an infinite number of multiples of 100. 100, 200, 300,400, ....
