Question

test the divisibility of the following numbers by 11:
1. 61809
2. 38016
3. 60847​

Answer 1

Answer:

some of odd digits - sum of even digits

1. (6+8+9) - ( 1+0)

23+ 1

22

22 is a multiple of 11

if the answer (22) is 0 or a multiple of 11 then the number is divisible by 11

so, 61809 is divisible by 11

Answer 2

Step-by-step explanation:

1.61809 - sum of odd numbers = 1+0+9 = 10

sum of even numbers = 6+8 = 14

= 10-14 = -11

11 is divisible to -11

so it is divisible by 11

2. 38016 - sum of odd numbers = 3+0+1=4

sum of even numbers =8 +6= 14

=4-14 = -10

11 is not divisible to -10

so it is not divisible by 11

3. 60847 - sum of odd numbers = 0+7= 7

sum of even numbers = 6+8+4= 18

= 7-18 = -11

-11 is divisible to 11

so it is divisible by 11
