将这些体积按从大到小的顺序排列。

2.35 l	2 l 305 ml	$2\frac{3}{5}$ l

1. Convert all volumes to millilitres for easy comparison

$2.35\text{ l} = 2.35 \times 1000\text{ ml} = 2350\text{ ml}$
$2\text{ l } 305\text{ ml} = 2000\text{ ml} + 305\text{ ml} = 2305\text{ ml}$
$2\frac{3}{5}\text{ l} = 2.6\text{ l} = 2.6 \times 1000\text{ ml} = 2600\text{ ml}$

2. Arrange the volumes from largest to smallest

Comparing the values in millilitres:
$2600\text{ ml} > 2350\text{ ml} > 2305\text{ ml}$
Therefore, the order is $2\frac{3}{5}\text{ l}$, $2.35\text{ l}$, $2\text{ l } 305\text{ ml}$.
