Math Question: What is the sum of the digits in the number 9920 multiplied by the quotient of dividing it by 8?

To find the sum of the digits, we have 9 + 9 + 2 + 0 = 20. Also, dividing 9920 by 8 gives us 1240. Therefore, the calculated value is 20 multiplied by 1240, which equals 24,800.

Math question: If the number 9920 is divided by 8 and then multiplied by 5, what is the result?

To find the result, we divide 9920 by 8, which gives us 1240. Then, we multiply 1240 by 5, resulting in 6200. Thus, dividing 9920 by 8 and then multiplying by 5 gives us the result of 6200.

Question: What is the largest prime factor of the number 9920?

To find the largest prime factor of 9920, we need to factorize it. By dividing it by the smallest prime, 2, we get 9920 = 2 * 4960. Continuing this process, we find that 4960 = 2 * 2480, and 2480 = 2 * 1240. Further, 1240 = 2 * 620, and 620 = 2 * 310. Next, dividing 310 by 2, we get 310 = 2 * 155. Finally, we find that 155 = 5 * 31, and both 5 and 31 are prime numbers. Therefore, the prime factorization of 9920 is 2 * 2 * 2 * 2 * 2 * 5 * 31. The largest prime factor is 31.
