# What is the divisibility rule of 11?

Here’s an easy way to test divisibility by 11. Take the alternating sum of the digits of the number, reading from left to right. If it’s divisible by 11, then so is the original number. For example, 2728 has an alternating sum of digits 2 – 7 + 2 – 8 = 11. Since 11 is divisible by 11, so is 2728.

## What is the divisibility rule of 11 with example?

A number is divisible by 11 if the difference between the sum of its odd digits and the sum of its even digits is either 0 or a multiple of 11.

## What is the divisibility rule of 11 class 6?

A number is divisible by 11 if the difference between the sum of its odd digits and the sum of its even digits is either 0 or a multiple of 11.

## What is the divisibility rule of 11?

The divisibility rule for 11 is a simple mental arithmetic that checks whether the number 11 completely divides another number. The rule of divisibility by 11 states that if the difference between the sum of the digits in the even and odd places is 0 or divisible by 11, then the number is divisible by 11.
