Answer: She will have 200 milliliters of lemonade left after filling the bottles.
Explanation:
Hi, since 1 liter = 1000 milliliters
For 16.3 liters: 16.3 x 1000 = 16,300 milliliters (1 batch)
She made 2 batches.
16,300ml x2 = 36,600 milliliters
We have the total amount of lemonade in two batches; we have to divide it by the capacity of each bottle (400 ml), to calculate how many bottles she can fill.
36,600 milliliters / 400 milliliters = 81.5 bottles
She can fill 81 bottles and she will have a leftover of half a bottle.
Since each bottle is 400 milliliters, half of it:
400/2 = 200 milliliters
She will have 200 milliliters of lemonade left after filling the bottles.
