Questions & Step-by-Step Solutions

What is the rule for determining if a number is divisible by 11?
  • Step 1: Write down the number you want to check for divisibility by 11.
  • Step 2: Identify the positions of each digit in the number, starting from the right. The rightmost digit is position 1, the next is position 2, and so on.
  • Step 3: Separate the digits into two groups: those in odd positions and those in even positions.
  • Step 4: Add up all the digits in the odd positions to get a total sum for odd positions.
  • Step 5: Add up all the digits in the even positions to get a total sum for even positions.
  • Step 6: Subtract the sum of the even position digits from the sum of the odd position digits.
  • Step 7: Check if the result from Step 6 is divisible by 11. If it is, then the original number is divisible by 11.
