How we can separate the divisibility

Answers

Answered by shivamkumar969353

Answer:

Rule: Take the last digit and cross it out from the original number. Then double it. Subtract it from the “new” number which is the original number excluding the last digit. If the difference is divisible by 7, then the original number must also be divisible by 7.
