Math question: A certain number when multiplied by 2 and then divided by 5 equals 1830. What is the number?

Let's solve this equation step by step: Step 1: Let x be the unknown number. Step 2: Multiply x by 2 => 2x. Step 3: Divide 2x by 5 => (2x)/5. Step 4: Set (2x)/5 equal to 1830: (2x)/5 = 1830. Step 5: Multiply both sides by 5: 2x = 9150. Step 6: Divide both sides by 2: x = 4575. Therefore, the number is 4575.

Math question: What is the sum of the digits of the number obtained by multiplying 1830 by its reverse?

To find the reverse of 1830, we get 0831. Now, multiplying 1830 by 0831 yields 1520730. The sum of the digits in 1520730 is calculated as: 1+5+2+0+7+3+0 = 18. Therefore, the sum of the digits of the number obtained by multiplying 1830 by its reverse is 18.

Math Question: What is the sum of all the digits in the number 1830?

To find the sum of all the digits in the number 1830, we add the individual digits together. The digit 1 + digit 8 + digit 3 + digit 0 equals 12. Therefore, the sum of all the digits in the number 1830 is 12. Explanation: The number 1830 has four digits: 1, 8, 3, and 0. To find the sum of these digits, we add them together. The digit 1 contributes a value of 1, the digit 8 contributes a value of 8, the digit 3 contributes a value of 3, and the digit 0 contributes a value of 0. Adding these values together, we get 1 + 8 + 3 + 0 = 12. Hence, the sum of all the digits in the number 1830 is 12.
