Question

what is definition of test of divisibility??? please tell definition and and tell example for the test of divisibility​

Answer 1

Answer:

Divisibility of 3 and 9 is found by adding up all the digits in a number. If the sum of the digits is divisible by 3, the number is divisible by 3. If the sum is divisible by 9, the number is divisible by 9. ... If the last two digits of a number are divisible by 4, then the original number is divisible by 4.

example:- A number is divisible by 6 if it is divisible by 2 and 3 both. For example: 85806 is divisible by 6 because it is an even number so divisible by 2 and sum of its digits, i.e., 8 + 5 + 8 + 0 + 6 = 27 27 is divisible by 3. A number of 2 digits is divisible by 7 because 3 × 6 + 3 = 21.

hope it will help you
