Math Question: If 1851 is divided by the sum of its digits, what is the result?

To find the sum of the digits, we add 1+8+5+1=15. Therefore, when we divide 1851 by 15, we get 123.4. So, the result is 123.4.

Math question: If 1851 is divided by 9 and then multiplied by 7, what is the result?

To find the result, we first divide 1851 by 9, which gives us 205.6667. Next, we multiply 205.6667 by 7, giving us 1439.667. Rounding this decimal to the nearest whole number, the final result is 1440. Therefore, the result of dividing 1851 by 9 and then multiplying by 7 is 1440.

Math Question: If the number 1851 is divided by the sum of its digits, then multiplied by the difference between the units digit and the thousands digit, what is the result?

To solve the problem, we start by finding the sum of the digits: 1 + 8 + 5 + 1 = 15. Then we calculate the difference between the units digit and the thousands digit: 1 - 1 = 0. Now, dividing 1851 by 15 gives us 123.4. Finally, multiplying this quotient by 0 results in 0. Therefore, the answer is 0.
