There are 200 of them. Starting with 45*23 = 1035 and all the multiples of 45 up to 45*222 = 9990.
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.
All multiples of 3 have digits that add up to a multiple of 3. There are 333 multiples of 3 between 1 and 1000.
All the multiples of 5 between 1 and 51 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 These add up to 275.
All multiples of 3 have digits that add up to a multiple of 3. There are 333 multiples of 3 between 1 and 1000.
Multiples of 25 up to 1000 are: 25;50;75;100;125;150;175;200;225;250;275;300;325;350;375;400;425;450;475; 500;525;550;575;600;625;650;675;700;725;750;775;800;825;850;875;900;925;950;975;1000
All of its multiples from 3 to 999
All multiples of 12, such as 120, 600, 660.

There are 200 of them. Starting with 45*23 = 1035 and all the multiples of 45 up to 45*222 = 9990.

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.
All multiples of 3 have digits that add up to a multiple of 3. There are 333 multiples of 3 between 1 and 1000.
To find all the multiples of 30 up to 1000, we can start by dividing 1000 by 30, which equals 33 with a remainder of 10. This means the last multiple of 30 within 1000 is 990. So, the multiples of 30 up to 1000 are 30, 60, 90, 120, all the way up to 990.
15, 30, and 45 .
All the multiples of 5 between 1 and 51 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 These add up to 275.
