3, 6, 9, 12, 15 The mean is 9.
They are 90, 180, 270, 360, and 450.
5: 5, 10, 15 9: 9, 18, 27 If you are looking for the lowest common multiple between 5 and 9 it would be 45. By the way multiples are just counting by the number itself. e.g. 5, 10, 15, 20, 25, 30, 35 (just count by fives or if the number was anything else count by that number)
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
The first two multiples are 9 and 8.
Take the first number. Add it to itself. Keep adding that number to the total three more times. The first five nonzero multiples of 9 are 9, 18, 27, 36, and 45. Put another way, let each number equal x. The first five nonzero multiples of x are 1x, 2x, 3x, 4x and 5x.
The first 5 multiples of 9 are: 9, 18, 27, 36, and 45.
Traditionally, 0 is not listed among the first five multiples. To avoid confusion, questions will frequently say, "List the first five non-zero multiples of 9." The answer is 9, 18, 27, 36 and 45. If 0 is included, put it first.
First of all unless you go into decimals, there are only three multiples of 9 and they are 1,3,and 9.
The first 5 multiples of 5 are: 5, 10, 15, 20, 25 The first 5 multiples of 9 are: 9, 18, 27, 36, 45 The first 5 multiples of both 5 and 9 are: 45, 90, 135, 180, 225
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
0 isn't the first multiple of 9.
9, 18, 27.
"The" five multiples is wrong; there are infinitely many multiples for any number (except zero), not just five. To get those multiples, just use the definition of multiple. That is, you can do any of the following multiplications: 9 x 0 9 x 1 9 x 2 9 x 3 etc., also: 9 x (-1) 9 x (-2) etc.
3, 6, 9, 12, 15 The mean is 9.
9, 18, 27, 36, 45
9, 18, 27, 36 and 45.
