How two books make up 0.3 of the books in the story library of these 0.2 deal with conference rate and 0.4 deal with electronics interpret why the answer is 0.12 represent in this equation above.

Answer 1

The question states that 0.2 of the books in the story library deal with conference rate and 0.4 deal with electronics.

To find out how many books make up 0.3 of the library, we need to find the common multiple between 0.2 and 0.4. The common multiple of 0.2 and 0.4 is 0.4.

Now, we know that 0.4 represents the total number of books in the library that deal with electronics. Since we want to find out how many books make up 0.3 of the library, we need to find 0.3 times 0.4:

0.3 x 0.4 = 0.12

Therefore, 0.12 represents the number of books that make up 0.3 of the library.
