You can select 9 numbers for the first digit, 8 numbers for the second digit, and 7numbers for the third digit; so 504 (e.g. 9*8*7) different three digit numbers can be written using the digits 1 through 9.
9, 90 and 900
To make 20 with three different odd numbers, we can use the numbers 1, 7, and 12. 1 + 7 + 12 = 20. These numbers are odd because they cannot be evenly divided by 2. It's important to note that there are multiple combinations of three odd numbers that can add up to 20, such as 3 + 9 + 8 or 5 + 11 + 4.
9
If the numbers can be repeated and the numbers are 0-9 then there are 1000 different combinations.
27 = 3*936 = 4*945 = 5*927, 36, and 45 are three different numbers whose greatest common factor is 9.

Three and six you numbskull.
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25

You can find the mean by adding the numbers and dividing that number by how many numbers their is. For example 2 plus 5 plus 2 equals 9 and because there is the three numbers 2 5 and 9 you divide 9 by 3 and get 3 as an answer. This an a example as to how you find the mean.
The numbers are 8, 9 and 10.
1, 25 and 1024 are three examples.
