What is the Divisibility test of 7.. plz all follow me. Those who follow me I will Follow them back..​

Answer 1

Answer:

Step-by-step explanation:

Numbers Divisible by 7

To determine if a number is divisible by 7, take the last digit off the number, double it and subtract the doubled number from the remaining number. If the result is evenly divisible by 7 (e.g. 14, 7, 0, -7, etc.), then the number is divisible by seven. This may need to be repeated several times.

Example: Is 3101 evenly divisible by 7?

310 - take off the last digit of the number which was 1

-2 - double the removed digit and subtract it

308 - repeat the process by taking off the 8

-16 - and doubling it to get 16 which is subtracted

14 - the result is 14 which is a multiple of 7

Answer 2

Answer:

First, you have to take the last digit from the number

Now double it

Then subtract the left over digits to the number

Now divide the number with 7

If the result comes as a whole number ( without any points inside the number ) then it is divisible by 7
