To find the fraction of the total apples picked that were sold as fresh fruit, we need to find the number of apples sold as fresh fruit and divide it by the total number of apples picked.
Since 110 of the apples were discarded as defective, the number of apples remaining is the total number of apples picked minus 110.
Let's calculate the number of apples sold as fresh fruit:
Total number of apples picked - Number of apples discarded = Number of apples remaining
52 - 110 = 42
So, 42 apples were remaining after discarding the defective ones, and out of these, 300 were made into cider. The remaining apples were sold as fresh fruit.
Number of apples sold as fresh fruit = Number of apples remaining - Number of apples made into cider
42 - 300 = -258
It seems like there might be a mistake in the given information, as we cannot have a negative number of apples sold as fresh fruit. Therefore, we do not have enough information to calculate the fraction of the total apples picked that were sold as fresh fruit. The correct answer is "not enough information."

To find the total area of Oak Manor, we need to multiply the length and width of the town.
Length = 3.8 miles
Width = 4.2 miles
Total Area = Length * Width
Total Area = 3.8 miles * 4.2 miles
Total Area = 15.96 square miles
Therefore, the total area of Oak Manor is 15.96 square miles. The correct answer is "15.96 mi²" or "15.96 mi squared".
