Number of ways that the thousand digit can be odd = 5 (1, 3, 5, 7, or 9)

Number of ways that the hundred digit can be even = 5 (0, 2, 4, 6, or 8)

These two digits are always different. Total number of possible pairs = 5 x 5 = 25.

For each pair, the tens digit can be any one of 8 digits (it can't be the same as

either the thousands or the hundreds) = 8 possibilities for the tens digit.

For each of those, the units digit can be any one of 7 digits (it can't be the same as

the thousands, the hundreds, or the tens) = 7 possibilities for the units digit.

Total number of different numbers that can be written according to these rules =

25 x 8 x 7 = 1,400

2.4 million in numbers would be 2,400,000. In non-digit form it would be written out as two million and four hundred thousand.

In order to get the greatest number we want to try and get the biggest possible numbers in the hundred thousands, ten thousands and thousand places. There is no rule against the hundred thousands digit being 9 so it must be 9. The ten thousand digit needs to be twice the tens so it must be 8 while the tens is 4. The thousands digit is divided by the units, and the number is even. So thousands must be 6 and the units must be 2. Thus the hundreds must be 7. The number is 986,742
