Question: Find a number that satisfies the following properties: it has four distinct digits, it is divisible by 7, the sum of its digits is 19, and it is the largest possible number that meets these conditions.

To find the largest number satisfying the given conditions, we start by finding all four-digit numbers with distinct digits. The largest possible digit we can use is 9. Since the sum of the digits is 19, the only combination that works is 9 + 8 + 1 + 1 = 19. However, this number, 9811, is not divisible by 7. Hence, there is no number that meets all the given conditions within the range of four-digit numbers with distinct digits.

Math question: What is the sum of the digits of the number 7129?

The sum of the digits of the number 7129 is 19. To find this, we add the individual digits together: 7 + 1 + 2 + 9 = 19. The sum represents the total value obtained by combining all the digits in the number.

Question: If the number 7129 is multiplied by the sum of its digits, and then divided by the product of its digits, what is the result?

To solve this, we first find the sum of the digits: 7 + 1 + 2 + 9 = 19. Next, we calculate the product of the digits: 7 × 1 × 2 × 9 = 126. Finally, we divide 7129 by 126: 7129 ÷ 126 = 56.6190476 (rounded to 10 decimal places). Therefore, the result of multiplying 7129 by the sum of its digits and dividing by the product is approximately 56.6190476.
