1.83 litres
=================
Combine the volumes of the 1.5 litre bottles and the 330ml can. First, it's important to note that 1 litre is equivalent to 1000 milliliters (mL), making the conversion between these units straightforward.
Since 1 litre equals 1000 mL, 1.5 litres can be converted to milliliters by multiplying by 1000:
Next, we add the volume of the can:
To find the total volume in liters, we convert 1830 mL back to liters by dividing by 1000:
Therefore, the total amount of lemonade is 1.83 litres.
