Answer 1

Divisibility rule of 7
A no. is divisible by 7 if 2 times the last digit of no. subtracted from the rest of the number is 0 or a multiple of 7

This can be carried out till you get single digit.
omit '-' if you get -ve Result.

============<<<>>>>===========
eg.
Test the divisibility of the no. 10283 by 7

1028-2(3)
= 1022

Now test it's divisibility too
Follow the same till you get single digit

102 - 2(2)
=98


9-16
= -7
=7
(Omit -ve sign)

So The no. 10283 is divisible by 7

Answer 2

Step-by-step explanation:

divisibility rule of 7::

★In the given number we have to see the last 3 digit and we have to subtract the remaining digit from the last 3 digits..★

and also we have to see that value which we have got whether it is divisible by 7 or not...

EG:

20720

720-20=700..

700 is divisible by 7....
