Question

2210978 divisible by 11 give reason

Answer 1

To check whether a number is divisible by 11, we find the sum of the digits in the even places and the odd places separately. Now, check the difference between the two sums if it is 0 or divisible by 11, then the given number is divisible by 11.

here,

odd digits are : 2 , 1 , 9 , 8

sum of odd digits = 2+1+9+8 = 20

even digits are: 2, 0, 7

sum of even digits = 2+0+7 = 9

their difference = 20 - 9 = 11 , is divisible by 11.
