61809 b) 38016 (6) 90728​

Answer 1

Answer:

61809 IS DIVIDBLE BY 11 AS IT GIVES US 5619 AS QUITENT

38016 IS DIVISIBLE BY 11 AS IT GIVES US 3456 AS QUITENT

90728 IS DIVISBLE BY 11 AS IT GIVES US 8248 AS QUITENT

Step-by-step explanation:

Answer 2

Step-by-step explanation:

a) 61809

Sum of odd place digits from the right = 9 + 8 + 6 = 23

Sum of even  place digits from the right = 0 + 1  = 1

Difference of the sums  = 23 - 1 = 22

Since 22 is divisible by 11 , the number , 61809 is divisible by 11 .

b) 38016

Sum of odd place digits from the right = 6 + 0 + 3 = 9

Sum of even  place digits from the right = 8 + 1 = 9

Difference of the sums = 9 - 9 = 0

Since the difference is 0 , the number , 38016 is divisible by 11 .

c) 90728

Sum of odd place digits from the right = 8 + 7 + 9 = 24

Sum of even  place digits from the right = 2 + 0 = 2

Difference of the sums = 24 - 2 = 22

Since 22 is divisible by 11 , the number , 90728 is divisible by 11 .
