Math question: The number 6870 can be expressed as the sum of two positive integers, such that the first number is 3 times the second number. What are the two numbers?

Let the second number be x. Hence, the first number would be 3x. Therefore, the equation is 3x + x = 6870. Combining like terms, we have 4x = 6870. Dividing by 4 on both sides gives x = 1717.5. However, since we're looking for positive integers, our second number must be a whole number, so we round it down to x = 1717. The first number would then be 3(1717) = 5151. Therefore, the two numbers are 5151 and 1717.

Question: Given the number 6870, what is the sum of its digits?

To find the sum of the digits in 6870, we add each digit together. Starting from the rightmost digit (0), we add 0 to the running sum. Moving to the next digit (7), we add 7 to the previous sum. Continuing with the next digit (8), we add 8. Finally, we add the leftmost digit (6). After these calculations, we get 0 + 7 + 8 + 6 = 21. Therefore, the sum of the digits in 6870 is 21.

Math question: What is the sum of the first 21 positive odd numbers, starting from 6870?

To find the sum of the first 21 positive odd numbers, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(2a + (n-1)d), where Sn represents the sum, n is the number of terms, and d is the common difference. In this case, a = 6870 (the first term) and d = 2 (as each subsequent term is 2 greater than the previous). Plugging in the values, we get Sn = (21/2)(2(6870) + (21-1)2) = 21(13740 + 40) = 21(13780) = 289,380. Therefore, the sum of the first 21 positive odd numbers starting from 6870 is 289,380.
