a number consists of 7 digits and the sum of all digits is one.what is the number?

1.000000

LOL, nah 0.500005

To find the number that consists of 7 digits and has a sum of one, we can start by reducing the problem to the minimum number of digits required. Since the question states that the sum of all digits is one, it implies that the remaining digits must be zero.

To form a seven-digit number, we want the first digit to be one, and all the remaining digits to be zero. Thus, the number will be in the form of 1 followed by six zeros.

The final answer is: 1000000.
