Question

Using divisibility rules, test the divisibility of 554785 by 11. Give reasons to support your answer

Answer 1

Answer:

39 is the answer

Step-by-step explanation:

add the odd numbers5+4+8=17

add the even numbers5+7+5=22

22+17=39

Answer 2

Answer:

To know that any number is divisible by 11, we have to add the odd number of digits = (5,7,5) and even number of digits = (5,4,8)

5 5 4 7 8 5

e o e o e o ( e = even, o = odd)

(5+7+5) = 17

-(5+4+8) = 17

Now if the result of subtraction will 0 or any number divisible by 11 such as 22,33 etc. the whole number will be divisible by 11.

As the result is 0 it is divisible by 11.
