Quizplus · Accepted Answer

To determine if a number is divisible by 11, subtract the sum of the digits in the odd positions from the sum of the digits in the even positions. If the result is a multiple of 11 (including 0), the original number is divisible by 11. For 6,703,279: (6+0+2+9) - (7+3+7) = 17 - 17 = 0. Since 0 is a multiple of 11, 6,703,279 is divisible by 11.
