If the digits of a number add up to a multiple of 3, then the number can be divided by 3. For example, the digits of 852 add up to 8 + 5 + 2 = 15. Since 15 is divisible by 3, 852 is divisible by 3.
Why don't you try multiplying 3 time 17 and seeing what you get? Hint, if you can add the individual numbers and get a number that can be divided by 3, the number can be divided by 3. Can 5 + 1 be divided by 3?
16/3 + 4 = 9.3 recurring (that is, 9.3333...)

no in order for it to be divisible by 3 add up all 3 numbers if that number can be divided then yes if not then no
-1/3 -1/3 times -1/3 is 1/9 -1/3 + -1/3 = -2/3, which is the same as -6/9.

No. Add the digits of the dividend and if that is divisible by 3 then the original number is divisible by 3; if not, its remainder when divided by 3 gives the remainder when the original number is divided by 3: 1 + 2 + 1 = 4 which gives a remainder of 1 when divided by 3, so 121 divided by 3 gives a remainder of 1. (121 = 40 x 3 + 1)
Yes; if 39 is divided by 3, you get 13. Another way to check this is add 13+ 13+ 13, and you will get 39.
First, divide 45 by 2, which equals 22.5. Then, add 3 to that result, giving you 22.5 + 3 = 25.5. Therefore, 45 divided by 2 plus 3 equals 25.5.
3 divided by 5 will tell you what 3 fifths is 3/5 = 0.6 Then add 2 2.0+0.6 = 2.6
