Answer:If Krista drank 3/16 of the water in her water bottle in the morning, 5/16 in the afternoon, and 3/16 in the evening, then the total amount of water she drank during the day is:
3/16 + 5/16 + 3/16 = 11/16
This means that the fraction of water that is left at the end of the day is:
1 - 11/16 = 5/16
Therefore, Krista has 5/16 of the water remaining in her water bottle at the end of the day.
