Question

Test the divisiblity by 11 7023643

Answer 1

Step-by-step explanation:

first we will mark digits of the numbers as even and odd:-

7-Even

0-Odd

2-Even

3-Odd

6-Even

4-Odd

3-Even

now add all evens and odds:

Even=7+2+6+3=18

Odd=0+3+4=7

now its difference=18-7=11

now 11 is divisible by 11 then 7023643 is divisible by 11.

Answer 2

Answer:

A number is divisible by 11,if the difference of the sum of its digits in odd places and the sum of its digits in even places,(starting from the unit's place)is either 0 or divisible by 11

The answer for your question is

7 0 2 3 6 4 3

⬆️⬆️⬆️⬆️⬆️⬆️⬆️

o e o e o e o

o=odd

e=even

then ,

sum of the digits in odd places

=3+6+2+7

=18

sum of the digits in even places

=4+3+0

=7

the difference of both are:-

=18-7

=11

Thus,11 is divisible by 11,so the number 7023643 is divisible by 11
