Question

The divisibily of 5 are that which has 0 or 1 in their unit place
The divisibily of 3 are which sum is divisible by 3
can you get the answer​

Answer 1

Answer:

Numbers, which last with digits, 0 or 5 are always divisible by 5.

Example: 10, 10000, 10000005, 595, 396524850, etc.

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, 38. To check whether 38 is divisible by 3 or not, take sum of the digits (i.e. 3+8= 11). Now check whether the sum is divisible by 3 or not. If the sum is a multiple of 3, then the original number is also divisible by 3. Here, since 11 is not divisible by 3, 38 is also not divisible by 3.

Similarly, 516 is divisible by 3 completely as the sum of its digits i.e. 5+1+6=12, is a multiple of 3.
