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 fraction of all the books in the school library that are both how-to books and deal with electronics.
In the equation provided, 0.12 represents the proportion of books in the school library that are both how-to books and deal with electronics.
To interpret what the answer 0.12 represents in the equation above, we first need to understand the given information.
According to the information provided, the school library contains 0.3 (or 30%) of books that are considered "how-to" books. Out of these "how-to" books, 0.2 (or 20%) are specifically about carpentry, and 0.4 (or 40%) are about electronics.
To find out what the answer 0.12 represents in the equation, we multiply 0.3 (the total proportion of "how-to" books) by 0.4 (the proportion of "how-to" books that deal with electronics):
0.3 × 0.4 = 0.12
Therefore, the answer 0.12 represents the proportion (or percentage) of "how-to" books in the school library that deal with both "how-to" and electronics. In other words, it signifies that 12% of the "how-to" books in the library are specifically related to electronics.
