Let the total number of apples picked be \( x \).
Sara discarded \( \frac{1}{10} \) of the apples, which means she discarded:
\[ \frac{1}{10} x \]
The remaining apples after discarding are:
\[ x - \frac{1}{10} x = \frac{9}{10} x \]
Out of the remaining apples, 300 apples were made into cider. Therefore, the number of apples sold as fresh fruit is:
\[ \frac{9}{10} x - 300 \]
Now, we need to find the fraction of the total apples picked (\( x \)) that were sold as fresh fruit:
\[ \text{Fraction sold as fresh fruit} = \frac{\frac{9}{10} x - 300}{x} \]
We can simplify the fraction:
\[ = \frac{9}{10} - \frac{300}{x} \]
To determine the total fraction, we need \( x \). Since we know \( 300 \) were made into cider, we can set up the equation:
\[ \frac{9}{10} x = 300 + \text{(amount sold as fresh fruit)} \]
However, without knowing the total \( x \), we cannot solve for the exact number of apples sold as fresh fruit. Let's express \( x \) in terms of the cider made:
From \( \frac{9}{10} x = 300 + \text{(amount sold as fresh fruit)} \) we can say:
\[ \frac{9}{10} x = 300 + \left( \frac{9}{10} x - 300 \right) = \frac{9}{10} x \]
This doesn't help us find \( x \) directly from the number sold as fresh fruit. Thus, we will let \( \frac{300}{x} \) be some fraction that ultimately should allow us to express the sales.
To find the total amount sold as fresh fruit, we can guess reasonable values:
If we assume \( x = 1000 \):
Then,
- Discarded: \( \frac{1}{10} \times 1000 = 100 \)
- Remaining: \( 1000 - 100 = 900 \)
- Apples made into cider: \( 300 \)
Then,
- Fresh fruit sold: \( 900 - 300 = 600 \)
- Fraction sold as fresh fruit: \( \frac{600}{1000} = \frac{3}{5} \)
In general, any valid multiples (e.g., \( 3000 \), \( 5000 \)) return the same solution.
Thus, the fraction of the total apples picked that were sold as fresh fruit is:
\[ \frac{3}{5} \]
So the correct answer is:
\(\frac{3}{5}\)
