Answer

\( 9,824,411 \) is not divisible by \( 11 \).

Solution

To determine if \( 9,824,411 \) is divisible by \( 11 \), we can use the divisibility rule for \( 11 \). According to this rule, a number is divisible by \( 11 \) if the difference between the sum of the digits in the odd positions and the sum of the digits in the even positions is either \( 0 \) or divisible by \( 11 \). Let's break down the digits of \( 9,824,411 \): - Odd position digits: \( 9, 8, 4, 1 \) - Even position digits: \( 2, 4, 1 \) Now, we will calculate the sums: 1. Sum of the odd position digits: \[ S_{\text{odd}} = 9 + 8 + 4 + 1 \] 2. Sum of the even position digits: \[ S_{\text{even}} = 2 + 4 + 1 \] Next, we will find the difference: \[ D = S_{\text{odd}} - S_{\text{even}} \] Let's calculate these values step by step. 1. Calculate \( S_{\text{odd}} \): \[ S_{\text{odd}} = 9 + 8 + 4 + 1 = 22 \] 2. Calculate \( S_{\text{even}} \): \[ S_{\text{even}} = 2 + 4 + 1 = 7 \] 3. Calculate the difference \( D \): \[ D = 22 - 7 = 15 \] Now, we check if \( D \) is divisible by \( 11 \): - \( 15 \) is not divisible by \( 11 \). Thus, \( 9,824,411 \) is **not** divisible by \( 11 \). The answer is **No**.

Beyond the Answer

To determine if \( 9,824,411 \) is divisible by 11, we can use the divisibility rule for 11, which states that you subtract the sum of the digits in the odd positions from the sum of the digits in the even positions. For the number \( 9,824,411 \): - Odd positions: \( 9 + 8 + 4 + 1 = 22 \) - Even positions: \( 8 + 2 + 4 + 1 = 15 \) - Now, subtract: \( 22 - 15 = 7 \) Since \( 7 \) is not divisible by \( 11 \), the answer is **No**. And remember, when you're trying to test for divisibility by 11, keep an eye on those digit positions! A little subtraction can save you from a lot of confusion. Just think about this handy rule whenever you're faced with large numbers; it can make calculations less daunting and a bit more fun!
