All the even numbers and all the odd multiples of 5.
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.
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.
12,24,36,48,60,72,84,96
Just 99.
The multiples of 7 under 100 are :7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98. the multiples of 11 under 100 are :11, 22, 33, 44, 55, 66, 77, 88, 99
All the even numbers and all the odd multiples of 5.
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, ....
9,18,27,36,45,54,63,72,81,90,99
