you would add 8-making the number 550.550 divided by 10 is 55
9 or 19 or 29 or 39 or 49 or 59 and so on and so forth. You could also add negative one, negative eleven, etc.

If you can add the integers and they add up to a number divisible by 3, then the number is divisible by 3.
Yes. If the integers making up the number add to a number divisible by 3, then it is divisible by 3.The integers 34215 add up to 15, so it is divisible by 3.34215/3 = 11405
Add 2.
you would add 8-making the number 550.550 divided by 10 is 55
in-
87 is already divisible by 3, so you could add a 0, 3, 6 or 9 anywhere in there and get the same result.
9 or 19 or 29 or 39 or 49 or 59 and so on and so forth. You could also add negative one, negative eleven, etc.
The lowest number you could add to make it divisible by 10, 2, and 5 would be 7. 23 + 7 = 30 30/10 = 3 30/2 = 15 30/5 = 6 Also, technically, you could add (-3) to make 20. 23 + (-3) = 20 20/10 = 2 20/2 = 10 20/5 = 4 Basically, you could add any number to 23 that would get a multiple of 10, since 2 and 5 are both factors of 10 to begin with.
The next nearest number divisible evenly by 10 would be 250 so you need to add 7 ro 243

To find out if 640 is divisible by 3, we will add up the numbers that make 640 as follows: 6 + 4 + 0 = 10 We know that if the sum of the numbers that make up 640 is divisible by 3, then 640 is divisible by 3. Since 10 is NOT divisible by 3, 640 is also NOT divisible by 3. Thus, the answer to the question "Is 640 divisible by 3?" is NO. If you divide 640 by 3, you get 213.3333333.
If you can add the integers and they add up to a number divisible by 3, then the number is divisible by 3.
243+7 = 250/10 = 25
542 - 387 add 3 to each number => 545 - 390add 10 to each number => 555 - 400 = 155.
