The ratio of the number of fiction book is 9:4, the different between the number of fiction and non fiction is 245
Evgesh-ka [11]

Answer:

Step-by-step explanation:

The ratio of the number of fiction books is 9:4

 the difference between the number of fiction and nonfictionn is 245

so if the number of fiction books = 9x

then the number of nonfiction books = 4x

then difference = 9x-4x = 5x

the difference is given 245

then 5x= 245

x=\frac{245}{5}=49

number of fiction books =49×9=441

number of nonfiction books =49×4=196
