You can ONLY use the following numbers:

11.3,
11.6,
12.9,
12.7,
11.5,
9.8,
9.4,
8.5,
8.4

The Challenge: The goal is to come up with as many SMALL combinations of numbers (using the numbers above), when averaged, equals to 11.5

For example: 11.3 + 11.6 + 11.6 / 3 = 11.5 (average)

The is a fun challenge. I've come up with eight ways. Can you beat me? I'll post results later.
