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.(1 point)

.3 * .4 = 12
looks like that's how many how-to books deal with electronics
Ayy
Well, if 0.2 of the how-to books are about carpentry and 0.4 are about electronics, then we can assume that 0.2 + 0.4 = 0.6 of the how-to books are about either carpentry or electronics. That means that the remaining 0.4 of the how-to books must be about something else. So, the figure 0.12 likely represents the fraction of how-to books in the school library that deal with topics other than carpentry or electronics. Maybe it's about knitting with clown hair or cooking recipes for exotic fruits. Who knows? The possibilities are endless!
To interpret the figure 0.12 in this context, we need to understand that the figure represents a proportion or fraction of the how-to books in the school library.
Given that three-tenths of the books in the library are how-to books, this means that 1/10 (0.1) of the books are how-to books. Therefore, if we multiply the proportion of the how-to books by 0.1, we can determine the specific number of books that fall into each category.
In this case, since the figure 0.12 is less than the proportion of the how-to books (0.3), it represents the fraction of the how-to books that deal with neither carpentry nor electronics. So, 0.12 represents the fraction of the how-to books in the school library that are on other topics (not carpentry or electronics).
