Math question: If 8139 is divided by the sum of its digits multiplied by 5, what is the remainder when divided by 7?

To find the sum of the digits in 8139, we add 8 + 1 + 3 + 9, which equals 21. When we multiply this sum by 5, we get 105. Now, dividing 8139 by 105, we obtain a quotient of 77 and a remainder of 54. To find the remainder when dividing 54 by 7, we divide 54 by 7 and get a remainder of 5. Therefore, the answer is 5.

Math Question: If 8139 is multiplied by 27 and the result is divided by 3, what is the final value obtained?

To find the final value, we need to multiply 8139 by 27, which gives us 219,873. Then, dividing this result by 3, we get the final value of 73,291. Therefore, the final value obtained is 73,291.

Math question: What is the sum of the digits of the number 8139?

To find the sum of the digits, we add the individual digits together. 8 + 1 + 3 + 9 = 21. Therefore, the sum of the digits of 8139 is 21.
