Question

divisiblity test of 11 of number 5500 , 871245​

Answer 1

Answer:

Step-by-step explanation:

If in any number the sum of the numbers in the even positions = sum of the odd numbers in the odd positions, then the number is divisible by 11. Alternatively, the difference of the sum of the numbers in even positions and the sum of the numbers in the odd positions = 11. Example

5500 even places=5,0

odd places=5,0

5+0-5+0=0 and 0 is divisible by 11

871245 even places = 8,1,4

oddplaces=7,2,5

13-14=-1 not divisible by 11
