Question

There are 4, 000 books in the towns library. Of these, 2, 600 are fiction. Write a percent equation that you can use to find the percent of the books that are fiction. Then solve your equation.

Answer 1

The percent equation showing the fiction books is y = 0.65x showing that among the 4,000 books in the library, 2,600 are fiction.

An equation is a mathematical representation of the equality of two expressions.

The number of books in the town's library = 4,000

The number of fiction books = 2,600

The number of nonfiction books = 1,400 (4,000 - 2,600)

The percentage of fiction books to the total number of books = 65% (2,600/4,000 x 100)

Let the total number of books in the library = x

Let the number of fiction books = y

Equation:

y = 0.65x

y = 2,600 (0.65 x 4,000)

Answer 2

15% of the books are fiction

Explanation:

We can divide every thing by 100 so it is easier

40----------100%

6--------------x

Cross multiplication

40x = 6*100

40x=600

Divide by 40

x=600/40

x=15
