There are x literature and art books in the library. There are 60 story books 3.2 times more than the literature and art books. How many literature and art books and story books are there in the library Using the equation,

There are y story books in the library
3.2x+60=y
Then, how many literary books and story books are there in the library, that is, x + y = x + 3.2X + 60 = 4.2x + 60

There are x books in the library, and 60 story books are 3.2 times as many as literature books (1) How many literary books and story books are there in the library? (2) When x = 320, how many literary books and story books are there in the library

(1) literature and art books: (X-60) △ 4.2
Story book: (X-60) △ 4.2 × 3.2 + 60 = (16x + 300) / 21
(2) literature and art books: (260-60) × 4.2 is not an integer
Storybook: (16 × 260 + 300) / 21 is not an integer
Note: is the data provided in the question accurate?

There are 600 literature and art books, 500 story books, and 45% science and technology books. How many literature and art books, science and technology books and story books are there in the library

(600 + 500) divided by (1-45%) = 2000 (copies)
I wish you progress in your study:)

There are 96 literature and art books, science and technology books and story books in the fifth grade library. It is known that science and technology books are 1 / 3 of story books and 25% of literature and art books. How many books are there in each of the three clocks?

If unit "1" is science and technology book, then story book is "3", literature and art book is "4"
1 + 3 + 4 = 8 (copies) 96 / 8 = 12 (copies) - Science and technology books
12 * 3 = 36 (copies) - story book
12 * 4 = 48 (copies) - literature and art books

There are 30 literature books, 25 story books, 45 science and technology books and 2500 story books. How many books are there in the library? How many books are there in the library

Total: 2500 divided by 25% is equal to 10000 science and technology books 0.45 * 10000 = 4500 literature and art books 0.3 * 10000 = 3000

There are 3 / 30 science and technology books and 1 science and technology book?

First of all, set the science and technology book as 1, and 3 / 7 of the science and technology book is equal to 1 * 3 / 7; then the story book is equal to 1 * 3 / 7 divided by 1 / 3, so the story book is 9 / 7 * 1
Second, science and technology books + story books = 94-30 = 64
Third, from the above, we can see that 1 (Science and technology book) + 9 / 7 * 1 (story book) = 64
Finally, science books = 64 divided by 16 / 7 = 28
