What is the largest four-digit number that is divisible by 3, even, and its digits add up to 18?

To find the largest four-digit number that satisfies all the given conditions, we need to consider the divisibility rule for 3. The sum of digits in a number is divisible by 3 if the number itself is divisible by 3. Since we want the digits to add up to 18, we ensure that the number itself will be divisible by 3. The largest four-digit number that meets this condition is 9999, where 9 + 9 + 9 + 9 = 36, which is divisible by 3.

Math question: If the number 9621 is multiplied by 3, added to 78, divided by 9, and then subtracted by 20, what is the result?

To solve this equation, we follow the order of operations: First, multiply 9621 by 3 to get 28863. Then, add 78 to obtain 28941. Next, divide by 9 to equal 3216.7778 (rounded to four decimal places). Lastly, subtract 20 to get the final result of 3196.7778.

Math question: What is the sum of the digits of the number 9621?

To find the sum of the digits of 9621, we add each digit individually: 9 + 6 + 2 + 1 = 18.
