Answer 1

The answer 0.12 in the equation \(0.3 \times 0.4\) represents the portion of the books in the library that are how-to books on electronics.

Here's the reasoning:

• The calculation starts with 0.3, which represents the proportion of all books in the library that are how-to books.
• The 0.4 represents the proportion of those how-to books that deal with electronics.

Therefore, when you multiply these two proportions (0.3 for how-to books and 0.4 for electronics), you get 0.12, which indicates that 12% of the total books in the library are how-to books specifically on electronics.
