Math question: What is the sum of the digits when 2785 is multiplied by 4, divided by 5, and subtracted by 1874?

Multiply 2785 by 4 to get 11140. Divide it by 5 to obtain 2228. Subtract 1874 to get 354. Now, let's find the sum of the digits in 354. The sum is 3 + 5 + 4 = 12.

Math question: Consider the number 2785. What is the product of its digits when multiplied together, and then divided by their sum?

To solve this, we first find the product of the digits: 2 × 7 × 8 × 5 = 560. Next, we calculate the sum of the digits: 2 + 7 + 8 + 5 = 22. Finally, we divide the product by the sum: 560 ÷ 22 = 25.4545454545... (rounded to decimal places). Therefore, the answer is approximately 25.4545454545...
