How-to books make up 0.3 of the books in the school library. Of these, 0.2 deal with carpentry and 0.4 deal with electronics. 0.3×0.4=0.12 Interpret what the answer 0.12 represents in this equation above.

The answer 0.12 represents the portion of the how-to books in the library that deal with both carpentry and electronics.
The answer 0.12 represents the portion of the how-to books in the library that specifically deal with both carpentry and electronics.
In the equation 0.3 × 0.4 = 0.12, the answer 0.12 represents the portion of the how-to books in the school library that are about either carpentry or electronics.
To understand this, we need to break down the equation.
First, we are given that how-to books make up 0.3 of the books in the school library. So, out of every 10 books in the library, 3 of them are how-to books.
Next, we are told that out of these how-to books, 0.2 deal with carpentry. This means that out of the 3 how-to books, 0.2 × 3 = 0.6 books are about carpentry.
Similarly, we are also told that 0.4 of these how-to books deal with electronics. So, out of the 3 how-to books, 0.4 × 3 = 1.2 books are about electronics.
Now, to find the portion of the how-to books that are about either carpentry or electronics, we add the number of books about carpentry to the number of books about electronics: 0.6 + 1.2 = 1.8.
But this value is the number of books, not the portion. To express it as a proportion of the total number of books in the library, we divide it by the total number of books (10) and get 1.8/10 = 0.18.
Therefore, the answer to the equation 0.3 × 0.4 = 0.12 represents the portion of the how-to books in the school library that are about either carpentry or electronics, which is 0.18 or 18%.
