Question: If a number is multiplied by 9, then multiplied by 3, and the result is 2709, what is the original number?

To find the original number, we need to reverse the process. Divide 2709 by 3, then divide the result by 9. Using division, 2709 ÷ 3 = 903; then 903 ÷ 9 = 100. Therefore, the original number is 100. Explanation: The solution involves using inverse operations to undo the multiplication. Since the number is multiplied by 9 and then by 3, we need to divide the final result (2709) by 3 and then by 9 to isolate the original number. This is because division is the inverse operation of multiplication. Dividing 2709 by 3 gives us 903, and dividing 903 by 9 yields 100. Thus, 100 is the original number that, when multiplied by 9 and then by 3, gives us the result 2709.

Math question: What is the sum of all digits in the number 2709?

To find the sum of the digits in the number 2709, we add together each individual digit. In this case, the digits are 2, 7, 0, and 9. Adding them together, we get 2 + 7 + 0 + 9 = 18. Therefore, the sum of the digits in the number 2709 is 18.

Math question: What is the sum of all the odd numbers from 1 to 2709, excluding any number that is divisible by 3?

To find the sum, we can use the formula for the sum of an arithmetic series: S = (n/2)(a + l), where n is the number of terms, a is the first term, and l is the last term. First, let's determine the number of odd terms excluding those divisible by 3. The first odd number is 1, and the last odd number below 2709 is 2707. Since we are excluding numbers divisible by 3, we need to find a pattern within the odd numbers. For any three consecutive odd numbers, one will be divisible by 3. Therefore, we can infer that for every 6 consecutive odd numbers, only 2 will be divisible by 3, leaving us with 4 terms. To find the number of 6-term groups, we divide the total number of odd terms (2707) by 6: 2707 ÷ 6 = 451. Now we can calculate the sum of these terms within each 6-term group: S = (4/2)(a + l) = 2(1 + 5) = 12. So, the sum of the terms in each 6-term group is 12. Next, to find the sum of the 451 groups: Sum = 12 × 451 = 5412. Therefore, the answer is 5412.
