Add up all the numbers and divide that total by the number of numbers. 1+ 2 + 3 + 4 + 5 = 15 15/5 = 3 The average is 3
Only the number 1 will divide evenly into 3, 5, and 8.The smallest number that can be divided evenly by 3, 5, and 8 is the number 120.
3, looks as if you add 9 to the first number, then add 1, divide by 5, add 9, add 1, divide by 5 to get 3

Divide the number by 100 and then multiply the answer by 5. add the number with the answer.
the answer will always be 5
Nope. To work out if a number is a multiple of three - add all the digits in the number together. If the answer will divide by 3, then so will the original number. In this case, 5+8+0 = 13 - which doesn't divide by 3.

There are an infinite number of numbers between any two numbers. It is very easy to prove, add 2+3 and divide it by 2, you would get 5/2, right? Now you can add 2 + 5/2 and divide it by 2, and 5/2 + 3 and divide it by 2. And so on, and so forth.
Any of them. To get 50 to 30 you could... subtract 20 add -20 divide by 5/3 multiply by 3/5

To find the mean (average) of numbers you add then up a divide by the number of numbers you have. so add 51.2 51.3 and 51.6 then divide by 3. I'm not doing your homework for you though so you can do it yourself.
