Sagot :

Answer:

1130 non fiction

Step-by-step explanation:

F=fiction

NF=non fiction

F-678=NF

5F=8NF

so NF=5/8F

substitute:

F-678=5/8F

reduce:

3/8F=678

F=1808

NF=1130

There are 1130 non fiction books in the library.

Given that,

  • Ratio of fiction books (F) to non fiction books (NF) is 8:5.
  • 678 more fiction books in library.
  • We need to find the number of non fiction books.

According to the scenario, calculation of data are as follows,

[tex]\frac{F}{NF} = \frac{8}{5}[/tex]

or 5F = 8NF

Now, NF = F-678

By putting the value, we get

5F = 8 ( F - 678)

5F = 8F - 5424

3F = 5424

F = 1808

So, By putting in 1st eq. we get,

5 [tex]\times[/tex] 1808 = 8NF

NF = 9040 [tex]\div[/tex] 8

NF = 1130

Non fiction books = 1130 books.
