If each numbers is 83333⅓, then they will add up to 1,000,000.
There are many sets of 12 numbers adding up to a million.
We can find whole numbers, too:
6 of the numbers can be 125000, so 6×125000=750000. 5 can be 41667, so 5×41667=208335.
And the last number would be 41665.
125000+125000+125000+125000+125000+125000+41667+41667+41667+41667+41667+41665.
And there are many others sets of 12, including 11×83,333+83,337=1,000,000.
