Thirds and Differences (Posted on 2005-07-21) Difficulty: 2 of 5

Arrange the digits 1-9 so that the first 3 form a number that is 1/3 of the number formed by the last three and the three digits in the middle form a number that is the difference between them.

The numbers are as they appear, not summed.
