No. It has four digits and each one of these is in a different place. No. It has four digits and each one of these is in a different place. No. It has four digits and each one of these is in a different place. No. It has four digits and each one of these is in a different place.
In order to make the number as big as possible, you would want the greatest value digits in the greatest place value. Thus the first number would have to be 9. Once 9 has been used, the second number would have to be 8. Then the third number would have to be 7 and so on. Therefore, the greatest 9 digit number with 9 different digits is 987,654,321.
The two sets of digits have different place values.
To order the numbers, compare the place value column digits starting with the highest place value column and moving right a digit when the comparison is the same until all the place value digits have been compared. For {0.25, 0.53, 0.8, 0.78, 0.6} they all have 0 as the units digit, but different tenths (first after decimal point) digits, so order based on the tenths digits, leading to {0.8, 0.78, 0.6, 0.53, 0.25} from greatest to least.

It's the number that has more digits to the left of the decimal point (if there is no decimal point, it's the number with more digits). If the number of digits to the left of the decimal point is the same, find the position farthest to the left where the digits are different. The number with the greater of those two digits is the greater number. For example, 10000 is greater than 9999 because 10000 has more digits, and 6350 is greater than 6349 because the farthest-left position that is different is the tens place, and 5 is greater than 4.

The positional place values of digits in negative numbers are in ascending order from least to greatest as for example in the number -987 the least value digit is 9 and the greatest value digit is 7 because -900 < -80 < -7 The positional place values of digits in positive numbers are in descending order from greatest to least as for example in the number 987 the least value digit is 7 and the greatest value digit is 9 because 900 > 80 > 7

If the digits go from the thousands place to the ones place then we need to use 4 digits. Because the digits are all even, we are forced to use the 4 even digits (2, 4, 6 and 8). As they decrease by 2 each time, the only option for ordering them is greatest to lowest. Therefore, the number described in the question is 8,642.
Each of the digits moves one position to the left. You might also say that the decimal point (explicit or implicit) moves one position to the right.
