```none

ID|Class | Number
--+------+---------
1 | 1    |  58.2
2 | 1    |  85.4
3 | 2    |  28.2
4 | 2    |  55.4

```

The desired result would be:

```none
Column1 |Number | Column2 | Number
--------+-------+---------+---------
1       | 58.2  | 2       |28.2
1       | 85.4  | 2       |55.4

```

What would be the required SQL?
