math

can somebody help me to check my answer

Identify if the first number is divisible by the second number, and if so, the reason why.
Is 216 divisible by 3?
A. No
B. Yes, because the sum of 2 + 1 + 6 = 9, which is divisible by 3.
C. Yes, because the last digit is 6, which is divisible by 3.
i am i think it is either b or c

8. abc = 100 a + 10 b + c
a + b + c = 9

a b c / 3 = (100/3)a + (10/3 ) b + c/3

= 331/3 a + 3 1/3 b + c/3
= (33 a + 3 b) + (1/3)(a+b+c)
well if a+b+c is divisible by 3, we are there

13. NO, 26 is NOT divisible by 3
8 * 3 = 24
9 * 3 = 27

note
2+4 = 6 divisible by 3
2+7 = 9, divisible by 3

2 + 6 = 8 NOT divisible by 3
