Final answer:
Winifred drinks more water than is initially in the bottle, so no water will remain.
Step-by-step explanation:
To find the fraction of a quart of water that will remain in the bottle, we need to subtract the amount of water that Winifred drinks from the total amount of water in the bottle.
Given that Winifred has 3/4 quart of water in the bottle and drinks 1/3 quart of water, we can subtract 1/3 from 3/4 to find the remaining fraction of water.
1/3 quart - 3/4 quart = (4/12) quart - (9/12) quart = (4-9)/12 quart = -5/12 quart
Since the result is negative, it means that Winifred drank more water than was initially in the bottle. Therefore, no water will remain in the bottle.
