Answer» We split the number in the form of power of 10's to prove the rule of divisibility of 3. The divisibility test for 3 is very important since it helps us to check if a number is divisible by 3. This is more useful in the case of larger numbers. It is known that we check if the sum of the digits is divisible by 3 to check its divisibility. Now, let's check how this rule is proved. |
