Question

solve the following showing the proccess​

Answer 1

Answer:

If the result after the subtraction of the sum of odd numbers from even numbers or vice versa is equal to 0 or divisible by 11 then the number is divisible by 11

Step-by-step explanation:

86611291=

First count the sum of odd digits=8+6+1+9=24

Next count the sum of even digits=6+1+2+1=10

Sum of Odd digits - Sum of Even digits=24-10=14

14/11 is not divisible therefore the number is not divisible.

Next all the same process.

Answer 2

Answer-7023643,58334661,602111213 are divisible by 11

Step-by-step explanation:

A number is divisible by 11 if the difference of sum of digiy at odd places and sum of digiy at even places is either 0 or divisible by 11

for example-example 1.

86611291

sum of odd places-8+6+1+9=24

sum of even places-,6+1+2+1=10

difference between odd places and even places-24-10=14 which not equal to zero

therefore it is not divisible by 11

example 2.

7023643

sum of odd places-7+2+6+3=18

sum of even places-0+3+4=7

difference between odd places and even places-18-7=11 which divisible by 11
