42, 48, and 54
54 72 90
6, 18, 30, 42, 54, 66, 78, 90
77.78%% rate:= 42/54 * 100%= 0.7778 * 100%= 77.78%
They are 42, 48 and 54
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96.

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.
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, . . .
All multiple of 18:18, 36, 54, 72 and 90
