Let the total number of apples picked be \( x \).
First, Sara discarded \( \frac{1}{10} \) of the apples, which means the number of defective apples is \( \frac{x}{10} \).
This leaves her with:
\[ x - \frac{x}{10} = \frac{10x}{10} - \frac{x}{10} = \frac{9x}{10} \]
So, after discarding the defective apples, Sara has \( \frac{9x}{10} \) apples remaining.
Out of these remaining apples, 300 were made into cider. Therefore, the number of apples sold as fresh fruit is:
\[ \frac{9x}{10} - 300 \]
To find the fraction of the total apples picked that were sold as fresh fruit, we need the fraction of apples sold as fresh fruit over the total apples picked, \( x \).
We can denote the number of fresh fruit sold as \( \frac{9x}{10} - 300 \). Thus, the fraction sold as fresh fruit is:
\[ \frac{\frac{9x}{10} - 300}{x} \]
To simplify this fraction, we can rewrite it as:
\[ \frac{9x}{10x} - \frac{300}{x} = \frac{9}{10} - \frac{300}{x} \]
Now, we need to find \( x \) to express the fraction. Since there is no additional information about the total number of apples, we need to assume \( x \) can be determined.
Given that the apples left after discarding were \( \frac{9x}{10} \), and that 300 were made into cider, we realize \( 300 ≤ \frac{9x}{10} \).
Now let's solve for \( x \):
\[ 300 = \frac{9x}{10} \]
Multiplying by 10:
\[ 3000 = 9x \]
\[ x = \frac{3000}{9} = 333.33 \ldots \]
Rounding isn’t feasible, but knowing that she's actually selling some portion could help through the fruit. If we assume she sold fresh fruit after making cider:
Using \( x \) to find how many were sold:
Let’s plug back into the formula for fresh fruit:
Fresh fruit sold = \( \frac{9 \cdot 333.33 \ldots}{10} - 300 = 300 - 300 = 0 \).
Given 300 became cider, if selling apples total turned out integers aligning \( 300 = \frac{9x}{10} \) becomes \( x=333.33 \ldots\) leads to none left for fresh food.
Among given answers, completion indeed lacks inconsistent denotations.
If an integer value approximating \( x = 300 \) would allow for \( \frac{9x}{10} - 300 \geq 0 \) hence fraction involved equating rests on practical values.
From potential correctly assumed states:
If 300 means maximum yields may show fresh from remainder evaluating just fruit sold:
Selling fresh represents calculated bits of apples leading to a fraction ratio formally but best estimate aligns towards \( \frac{3}{10}.\)
