a cool way to know the multiples of 9 is...here I'll show you...
9
18
27
36
45
54
63
72
81
90
18 is backwards 81.27 is backwards 72.36 is backwards 63.45 is backwards 54.hope this helped!!!
(PS:you can also tell cuz the first digit of every number goes up one and the second digit of every number goes down one.)I'm only in like sixth grade too!
They are the infinitely many multiples of 990.
11 of them.
There are 11 multiples of 9 up to 100. 9 18 27 36 45 54 63 72 81 90 99
The numbers 3, 5, 7, 9, 11, 13, 15, 17, and 19 are not multiples of 2.
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.
The common multiples of 9 and 11 are 99, 198, 297 and so on.
They are the infinitely many multiples of 990.
11
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495
11
Well, 99
Any multiple of 99.
11 of them.
99 and all its multiples...
