Answer 2

Answer:

• To check whether 9220816 is divisible by 11 or not firstly you should know divisibility rule of 11 that is

◼ sum of numbers at odd place - sum of nuber at even place if the ans you got is 0 or the number which is divisible by 11 then the whole number will be divisible by 11

➡➡➡ 6 +8+2+9 = 25

➡➡➡ 1 + 0 +2 = 3

➡➡ 25 - 3 = 22

▶ 22 is divisible by 11 hence 9220816 is also divisible by 11

• to check whether 394578 is divisible by 3 or not :-

divisibility rule of 3 = sum of all numbers

= 3+9+4+5+7+8 = 36

▶36 is divisible by 3 hence 394578 is also divisible by 3
