use divisiity test to find which of the following numbers are diviside by11
b) 5.00.005
38.53.935​

Answer 1

U can test all the divisibility by :-

(sum of odd places – sum of even places)

i am not getting ur digits so i have not write the answers.

u will surely get the answer by this method

ex. - 121

odd places = 1+1=2

even places = 2

diff. = 2-2 =0

if ur difference is 0 or a multiple of 11 it means that no. is divisible by 11
