Answer:
Divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3. Consider a number, 308. To check whether 308 is divisible by 3 or not, take sum of the digits (i.e. 3+0+8= 11). Now check whether the sum is divisible by 3 or not.
Step-by-step explanation:
If the sum of the digits of a number is
divisible by 3, then the number is divisible
by 3. Some examples of numbers divisible
by 3 are as follows. The number 85203 is
divisible by 3 because the sum of its digits
8+5+2+0+3=18 is divisible by 3.
