The first 10 multiples of 9 have digits that always sum to make 9, which can make them easier to memorise. For example, when looking at the numbers of 9, 18, 27 and 36, we have 9 = 9, 1 + 8 = 9, 2 + 7 = 9 and 3 + 6 = 9. This pattern continues all the way up to 90, which has 9 + 0 = 9.
Hereof, What is the pattern of 9? 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108. After listing the multiples of nine up to 108, we added the digits of each multiple and discovered that each answer was equal to 9 (with 99; 9 + 9 = 18; then 1 + 8 = 9).
What are factors of 9? Factors of 9 are 1, 3, and 9. 1 is a universal factor. Factors of a number are the numbers we multiply to get that particular number.
Additionally How many multiples of 9 are found? Question 2

What is the sum of the multiples of 9?
Why do the digits of multiples of 9 add up to 9?
The main thing that the digits of multiples of 9 add up to 9 because we use a base-10 system. First, let’s take 9 and re-write it as 09. When we add a 9, the value of the 10’s place will go up by 1, but the value of the one’s place will go down by 1 because there wasn’t a “complete 10 for the 9.”

What is the answer of 3 is a factor of?
Again 3 is a factor of 12 because 3 divides 12 without leaving a remainder. The factors of 12 are 1, 2, 3, 4, 6, and 12, because each of those divides 12 without leaving a remainder (or, alternatively, each of those is a counting number that can be multiplied by another counting number to make 12).
Which of the following is divisible by 3 and 9? Every number divisible by 9 is divisible by 3. For example, 7425 is divisible by 9, hence it is divisible by 3. However, a number divisible by 3 is not necessarily divisible by 9. For example 6, 12, 15, 21, 24, 30 are all divisible by 3 but none of them is divisible by 9.
