1. Set the science and technology book as 1, and 3/7 of the science and technology book is equal to1* 3/7; Then the storybook is equal to 1*3/7 divided by 1/3, so the storybook is 9/7* 1.

Second, science and technology books+story books =94-30=64.

Third, it can be seen from the above: 1 (science book) +9/7* 1 (story book) =64.

Finally, science and technology books =64 divided by 16/7=28.
