The idea of solving three small questions on page 86 of the fifth grade mathematics synchronous Soviet Education Edition is: the school library has three categories: science and technology books, story books and comic books. Science and technology books and The ratio should be: six sevenths (6/7) and two thirds (2/3), right?

Therefore, it can be seen that the total proportion of storybooks+science and technology books+storybooks+comics =6/7+2/3=32/2 1.

Proportion of three books = 1

So: the proportion of story books = 32/21-1=11.

The proportion of science and technology books = 1-2/3= 1/3.

Comic scale = 1-6/7= 1/7.
