Math question: What is the maximum possible number obtained by arranging the digits of 1278?

To find the maximum possible number, we need to rearrange the digits of 1278 in descending order. This gives us 8721. Therefore, the maximum number that can be obtained is 8721. Explanation: The given number 1278 has four digits: 1, 2, 7, and 8. To form the maximum number, we arrange these digits in descending order: 8, 7, 2, and 1. This yields the maximum number 8721.

Math question: What is the sum of the digits in the number 1278?

To find the sum of the digits in 1278, we add the four digits: 1 + 2 + 7 + 8 = 18.

Math question: What number is obtained by multiplying 1278 by the sum of its digits?

To find the sum of the digits of 1278, we add 1 + 2 + 7 + 8 = 18. Now, multiplying 1278 by 18, we get the result: 1278 * 18 = 22,932. Therefore, the number obtained by multiplying 1278 by the sum of its digits is 22,932.
