No.
Yes,
Yes, 285 divided by 5 = 57
There is no kind of math that I am aware of in which 2 + 8 + 5 = 6. It used to be called 'casting out nines' but more generally is called 'modular arithmetic.' To determine if a number such as 285 is divisible by 3 you add up the digits: 2 + 8 + 5 = 15, then if the answer is more than 9, add them up again: 1 + 5 = 6. If the final answer is 3, 6, or 9, the original number 285 was divisible by 3: 285 = 95 x 3. If the final answer is 9, the number was divisible by 9. So 1287 adds up to 18 and 1 + 8 = 9, so 1287 is divisible by 9. (1287 = 143 x 9.) If the answer is 3, 6, or 9 and the original number was even, it was divisible by 6.
Yes: 855 / 3 = 285
YES. 285 is divisible by 5. A number is divisible by 5 if it ends with 0 or 5
285 is divisible by these numbers: 1, 3, 5, 15, 19, 57, 95, 285.
No.
Yes,
Yes, 285 divided by 5 = 57
not by a whole number 280 and 290 are 285 / 10 = 28.5
No. Any odd number can not be divisible by an even number.
Yes, the result is 285.
