There are 222 numbers on that list. I'll do the first ten.
9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and just keep adding nine until you get to 1998.
They are: 9/1000 itself and its equivalent fractions such as 18/2000
They are multiples of 1, 3 and 9.
1, 3 and 9
1, 3, 7, 9, 21, 27, 63, and 189
9 of them.
The multiples of 9 are: 1 and 9 3 and 3
Since you didn't specify a single number, and all numbers are multiples of themselves, the first 2000 multiples are the counting numbers 1 to 2000.
1, 3 and 9 are common factors of 27, 45 and 81. 27, 45 and 81 are multiples of 1, 3 and 9.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
They are multiples of 1, 3, and 9.
1, 9, and 81 are the only multiples of 81
The factors of 9 are 1, 3, and 9. The multiples of 9 are 9, 18, 27, 36, 45,...etc.
the common multiples between 1 and 100 for 9 and 10 are just 90!
They are: 9/1000 itself and its equivalent fractions such as 18/2000
They are multiples of 1, 3 and 9.
