Question

write divisibility ruleof 11 explain with examples​

Answer 1

Step-by-step explanation:

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, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Answer 2

Answer:

Add the digits in blocks of two from right to left. The result must be divisible by 11.

example :627: 6 + 27 = 33 = 3 × 11.

Subtract the last digit from the rest. The result must be divisible by 11.

example : 627: 62 − 7 = 55 = 5 × 11.
