Question

State the dividiblity rules of 2,3,and 11​

Answer 1

Step-by-step explanation:

divisibility rule of 2 = numbers which have even numbers at its ones place. For ex - 234, 578, 430.

Divisibility rule of 3 = If the addition of the digits of that number is divisible by 3, the whole number is divisible by 3. For ex - 633 = 6 + 3 + 3 = 12 which is divisible by 3. Therefore the number 633 is divisible by 3.

Divisibility rule of 11 - If the number of digits is even, add the first and subtract the last digit from the rest. The result must be divisible by 11. If the number of digits is odd, subtract the first and last digit from the rest. The result must be divisible by 11. For ex - 121, 77, 44.

Answer 2

Answer:

DIVISIBILITY RULE OF 2

When 0,2,4,6,8 are at ones digit of any number the number will be divisible by 2.

Example = 542, 648

DIVISIBILITY RULE OF 3

If the sum of all the digits of a number is divisible by 3 so the number will be also divisible by 3.

Example= 942

9+4+2=15 so 15 is divisible by 3 that means the number is also divisible by 3.

DIVISIBILITY RULE OF 11

If the difference of sum of its number at odd and even place is 0 or any multiple of 11 so the number will also be divisible by 3.

Example= 123464

So 1,3,6 are at odd places so 1+3+6=10

and 2,4,4 are at even places so 2+4+4= 10

Now the difference 10-10=0 is 0 so the number is divisible by 11
