First, let's calculate how many liters of juice are in the punch bowl:
2 + 3.5 = 5.5
One hectoliter is equal to 100 liters. Based on this knowledge, we can set up an equation like this:

It states that one hectoliter is 100 liters and that x hectoliters is 5.5 liters. To solve, we can use cross-multiplication:


There are 0.055 hectoliters in the punchbowl.
