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 x 0.4=0.12 interpret what the answer 0.12 represents in this equation above.
The answer 0.12 represents the proportion of books in the school library that deal with both makeup and electronics, considering that 0.3 of the books are makeup books and 0.4 of the books are electronics books.
In the given equation, 0.3 x 0.4 = 0.12, the answer 0.12 represents a fraction of the total number of books in the school library that deal with both makeup and electronics.
To understand how we arrive at this interpretation, let's break down the given information and equation step by step:
1. The problem states that makeup books make up 0.3 (or 30%) of the total books in the school library.
2. Of these makeup books, 0.2 (or 20%) deal with carpentry.
3. Additionally, the problem mentions that 0.4 (or 40%) of the total books deal with electronics.
Now, let's focus on the equation 0.3 x 0.4 = 0.12:
1. The first value, 0.3, represents the fraction of all books that are makeup books.
2. The second value, 0.4, represents the fraction of all books that are electronics books.
3. By multiplying these two fractions together (0.3 x 0.4), we get the answer 0.12.
Therefore, the final result, 0.12, represents the fraction of all books in the library that deal with both makeup and electronics. In other words, 12% of the total books in the library deal with both of these subjects.
In the given equation, 0.3 represents the proportion of books in the school library that are makeup books. Similarly, 0.4 represents the proportion of makeup books that deal with electronics within the makeup book category.
When we multiply 0.3 by 0.4, we get 0.12. This means that 0.12 or 12% of all the books in the school library are makeup books that specifically deal with electronics.
