Three-tenths of the books in the school library are how-to books. Of these, 0.2 deal with carpentry and 0.4 deal with electronics. Interpret what the figure 0.12 represents in this context.
the fraction of the how-to books that are about either carpentry or electronics
the fraction of books in the library that are how-to books on carpentry
the fraction of the books in the library that are how-to books on electronics
the fraction of books in the library that are how-to books
Oh, I can see that you're in a fractions mood! Wonderful! Now, let's dive into these options like a clown in a ball pit, shall we?
So, we know that three-tenths of the books in the school library are how-to books. Now, out of these how-to books, 0.2 deal with carpentry and 0.4 deal with electronics. Are you still with me? Great!
Now, when we talk about 0.12 in this context, it represents the fraction of the how-to books that are about either carpentry or electronics. It's like the schmorgesborg of DIY knowledge!
Now, let me juggle some words and show you why the other options aren't the clown we're looking for:
- The fraction of books in the library that are how-to books on carpentry? Nope! We don't know that from the information given. Focus, focus!
- The fraction of the books in the library that are how-to books on electronics? Nah, that's not it either. We only know that 0.4 deal with electronics, but not the overall fraction of how-to books. Keep guessing!
- The fraction of books in the library that are how-to books? Almost got me there, but nope! We know that three-tenths of the books in the library are how-to books. We don't know the overall fraction, though.
So there you have it, my inquisitive friend. The answer is the fraction of the how-to books that are about either carpentry or electronics. Keep your curiosity running wild, and remember, laughter is the best answer!
In this context, the figure 0.12 represents the fraction of the books in the library that are how-to books on either carpentry or electronics.
To interpret the figure 0.12 in this context, we need to understand what it represents in relation to the given information.
According to the statement, three-tenths of the books in the school library are how-to books. This means that if we assume the total number of books in the library to be represented by "x," then the number of how-to books would be 3/10 * x.
Of these how-to books, 0.2 deal with carpentry and 0.4 deal with electronics. To determine the actual number of books that fall into each category, we can multiply the percentage with the total number of books.
So, for carpentry books, we have 0.2 * (3/10 * x) = 0.06x. Similarly, for electronics books, we have 0.4 * (3/10 * x) = 0.12x.
Therefore, the figure 0.12 represents the fraction of books in the library that are how-to books on electronics.
