Question

how do we find divisibility of 7​

Answer 1

Step-by-step explanation:

Divisible by 7 is discussed below: We need to double the last digit of the number and then subtract it from the remaining number. If the result is divisible by 7, then the original number will also be divisible by

Answer 2

Answer:

Step-by-step explanation:

divisible by 7: Take the last digit of the number, double it Then subtract the result from the rest of the number If the resulting number is evenly divisible by 7, so is the original number.

Divisibility by 7: The absolute difference between twice the units digit and the number formed by the rest of the digits must be divisible by 7 7 7 (this process can be repeated for many times until we arrive at a sufficiently small number).
