Question

Can anybody tell me how do we solve the divisibility rule of 11? Divisibility rule of 11 in the sense like divisibility of 3 we solve by adding all the numbers and we get our answer. So can somebody tell me how do we solve of 11? We use arrows and all that in, divisibiltity of 11 so I need that. Spam answers will be reported. So please answer if you know. Please help

Answer 1

Step-by-step explanation:

Difference of sum of alternate digits is divisible by 11

for example 209 which on dividing by 11 gives 19, i.e., an integer. therefore its divisible by 11.

(2+9)-0=11 which is divisible by 11

14641: (1+6+1)-(4+4)=0 which divisible by 11

Answer 2

Answer:

First, we will take an example 274

In this you have to add all odd numbers first

In this it is only 7 so the sum is 7

Then you have to add even numbers

In this they are 4 and 2, we will add them

We get the sum 6

Then you have to subtract both the sums

In this they are 7 and 6

So the difference is 1.

If the difference is 11 or 0 then the number is divisible by 11 and if the difference is 1,2,3,4,5,6 etc then it is not

So the following no. Cannot be divided by 11
