Final answer:
To find out how much more water the vase can hold, subtract the amount of water already in the vase from its total capacity.
Step-by-step explanation:
To find out how much more water the vase can hold, we need to subtract the amount of water already in the vase from its total capacity. First, convert 1 liter and 229 milliliters to milliliters by multiplying by 1000: 1 liter = 1000 milliliters. Then, add the milliliters: 1000 ml + 229 ml = 1229 ml. Next, add the additional milliliters: 1229 ml + 398 ml = 1627 ml. Finally, subtract the total amount of water in the vase from the capacity: 2419 ml - 1627 ml = 792 ml.
