Question

use divisbility test to determine wether 639210 is divisible by 11​

Answer 1

Answer:

Here an easy way to test for divisibility by 11.

Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number.

So, for instance, 639210 has alternating sum of digits 6+9+1=16 AND 3+2+0=5

now subtract both the values=16-5=11

as 11 is divisible by 11 so the no. is also divisible by 11
