Answer 1

The answer 0.12 represents the portion of books in the library that are how-to books on electronics.

Here's the reasoning: 0.3 represents the fraction of all books in the library that are how-to books, and 0.4 represents the fraction of those how-to books that deal with electronics. Therefore, when you multiply them (0.3 × 0.4 = 0.12), you find that 0.12 of all the books in the library are how-to books specifically focused on electronics.

Answer 3

To determine the fraction of the total apples picked that were sold as fresh fruit, we need to follow these steps:

1. Identify the total apples picked: Let's denote the total number of apples picked as \( x \).

2. Calculate the defective apples: Sara discarded \( \frac{110}{10} = 11 \) apples as defective.

3. Calculate the remaining apples: After discarding the defective apples: \[ \text{Remaining apples} = x - 11 \]

4. Calculate the apples made into cider: According to the problem, 300 apples were used to make cider.

5. Calculate the apples sold as fresh fruit: The remaining apples after cider production are: \[ \text{Fresh fruit sold} = (x - 11) - 300 \] which simplifies to: \[ \text{Fresh fruit sold} = x - 311 \]

6. Determine the fraction sold as fresh fruit: The fraction of the total apples picked that were sold as fresh fruit can be expressed as: \[ \text{Fraction} = \frac{\text{Fresh fruit sold}}{\text{Total apples picked}} = \frac{x - 311}{x} \]

Now, we need a specific answer based on possible options given. Since we don't have the actual value of \( x \) (the total number of apples picked), we are unable to compute a specific fraction.

Thus, based on the provided options, the correct response would be not enough information.
