Math question: If the number 1831 is multiplied by 4 and then divided by 7, what is the result?

To find the result of multiplying 1831 by 4 and dividing it by 7, first multiply 1831 by 4: 1831 * 4 = 7324. Then, divide the result by 7: 7324 / 7 ≈ 1046.2857 (rounded to four decimal places). Therefore, the result is approximately 1046.2857.

Math Question: The number 1831 is added to the product of multiplying two numbers, where one number is twice the other. If the sum of the two numbers is 205, what are the two numbers?

Let's assume the two numbers are x and 2x. According to the given condition, the equation can be formed as x + 2x + 1831 = 205. By simplifying, we have 3x + 1831 = 205, and by subtracting 1831 from both sides, we get 3x = -1626. Dividing both sides by 3 gives x = -542. Hence, the two numbers are -542 and -1084.

Math question: If the number 1831 is multiplied by 3 and then divided by 7, what is the result?

To find the result, we can express the calculation as follows: (1831 * 3) / 7 = 5493 / 7 = 784.7142857 (rounded to 9 decimal places) Therefore, when multiplying 1831 by 3 and dividing the product by 7, the result is approximately 784.7142857.
